This topic describes how to create a trial app on the Tuya Developer Platform, create an official OEM app, publish the app, and configure general parameters.

Build an OEM app

Create an app

1. Log in to the Tuya Developer Platform and go to the app page.

2. Click Create.

   

3. In the dialog box, complete the app information, carefully read and accept terms in OEM APP Service and Software License Agreement.

   Option	Description	Example
   App Name	The app name will be displayed on the user’s mobile phone desktop. We recommend that you enter a name within six characters in Chinese or 12 characters in English. If the specified maximum length is exceeded, app users cannot view the full name.	A branded smart product app
   App Package for Android/iOS	The unique identifier used for publishing on app stores. Try to include the company domain name to ensure a unique app package name. If the app package name already exists in an app store, the app cannot be published on the app store. Recommend letters and numbers. Three sections are recommended and they can be separated from each other with periods (.). Each section starts with a letter. The characters such as “tuya” cannot be used. For example, if the Tuya domain name is tuya.com, the package name can be set to com.tuya.smart.	com.testapp.smartiot
   Channel ID	Optional. If not specified, the channel ID is automatically generated based on the package name. The channel ID cannot be modified after it is confirmed. It is mainly used to evoke this app on the mobile phone and is also related to the link of the QR code to print.	–

Build an app

After the app configuration is completed, choose Next: Build App > Build. Then, the system builds each app package in the sequence of application time, and the page will prompt the estimated build time. After the app is built, the system pushes the build result to your account of Tuya Developer Platform by email or SMS.

• Launch Checklist: When you visit this page for the first time, this page displays the required configuration items for your app to be published on the app store. However, to optimize your tests and experience, you can click Build to build the app for tests in advance.

  

• If the app is built, you can use your mobile phone to scan the QR code to download and install the app for tests. The QR code automatically identifies the mobile phone system and supports both Android and iOS.

  

• In the very rare case that the build fails, an error message is returned to help you troubleshoot the error. You can also submit a ticket to request technical support.

  

Trial version of the app

The trial version is created and configured on the Tuya Developer Platform through the above process. After the app is built, you can scan the QR code for the trial version to download and install the app on your mobile phone.

• The trial version is valid for 30 days from the date of creation. The trial version cannot be edited or built after expiration, and the installed app on the mobile phone cannot be used as expected.
• The installation package of the trial version cannot be used to publish the app on the app store. You must purchase the OEM App service and complete the required configuration items before the app can be published on the app store.

Official version of the app

If you have already purchased the OEM App service, ignore this step and publish the app on the app stores.

Purchase OEM app service

If your app passes the test, you can publish the app on the app stores. If the OEM App service is not purchased, you cannot get the installation package for publishing. After the trial version expires, you cannot continue to use the app.

• Click Purchase OEM App and follow the instructions on the page to place an order and complete the payment.

  

• Select App: Select the app to be purchased.

• Company Developer Account: Prepare a developer account for the app stores in advance. We recommend that you register an overseas developer account in App Store.

• Invoice: You can choose whether to request an invoice. If you want an invoice, provide the invoice information after the service is completed and contact the Tuya staff to get an invoice.

After you select the payment method and complete the payment, you can return to the studio and continue to configure your app.

Publish the app

Method 1: Purchase the app publishing service

• When the app test is finished, click Next: Publish App.

  

  Note: After you modify the content in the development step, such as UI and extended functions, you need to rebuild the app.

• If you have not purchased the publishing service, we recommend that you purchase the app publishing service in advance. Because certain required functions of the app depend on third-party platforms, we provide related configuration services for Location, App Certificate, and Push Certificate.

  

• If you have already purchased the publishing service, the system will display a prompt, and the Tuya staff will contact you. You can ignore the steps for the publishing and the Tuya staff will complete the follow-up operations.

  

Method 2: Publish by yourself

1. After the app test is finished, click Next: Publish App. The system automatically checks the required items. When the app is not fully configured, the page will prompt you to configure it. You can click Configuration to configure one by one.

   

   Note: As long as any configuration item is modified, the app must be rebuilt to take effect. After the configuration is completed, you can rebuild the app. To accelerate the build process, we recommend that you complete all the configurations at once before building.

2. After the app is built, uninstall the previous app version and download and test the app of the later version. Check whether to enable or disable the Android push function and map function and continue to publish the app. The iOS push service can only be tested after the app is published.

3. You can upload and download the installation package for iOS on the platform. To pass the strict review of apps for iOS, carefully read the operation manual and publish your app according to the specifications.

   The installation package for iOS supports Android (Mainland China) and Google Play-specific packages. New installers to Google Play since August 2021 must use the app bundle file.

   • By default, the Android (Mainland China) package includes AutoNavi map service. It allows login with WeChat and Tencent QQ accounts and supports push notification services for multiple mobile phone brands.

   • The Google Play-specific package includes Google Maps and the push notification services.

     

4. (Optional) You can submit a ticket to consult and solve the problems when you publish the app.

5. After your app has passed the review, click Published at the bottom of the page to confirm that the app has been published on the app stores.

Required setting

To publish your app, the following functions are required.

User agreement or privacy policy

Click Add Version. You need to provide the custom content of the privacy policy and service terms.

Tuya provides Template Reference in multiple languages including Chinese, English, German, French, and Japanese. You can download and customize your content. To publish your app, versions in English are required.

Note: Tuya’s privacy policy and user agreement templates are for reference only. Upload your versions of the privacy policy and user agreement with accurate and legal content. If you follow the entire content of the template, Tuya shall not make any representations or warranties as to the applicability and application results of the specified template. To meet the mandatory regulatory requirements and improve privacy protection, Tuya will modify and publish the template content from time to time. You must check and update your privacy policy and user agreement if you follow the template content.

Certificate for iOS

If you want to publish your app on the App Store, you need to upload the relevant certificate here. To create a certificate, you need to register a developer account first. For more information, see the corresponding documents. If the certificate is not uploaded, the system will not be able to build an installation package, and the app cannot be published.

• Auto Generate Certificates (recommended): This function is an auxiliary function. The certificate preparation process of the iOS certificate platform is complex. You can enable the automatic generation and upload of all certificates. You only need to enter the authorization information to quickly complete the certificate configuration.

  

• Manually Create and Upload Certificates: For more information, see Making an iOS Certificate.

Certificate for Android

To publish your app on the Android app stores, upload the relevant certificate here. To create a certificate, you need to register an Android developer account first and configure the app as required by the app stores. For more information, see the corresponding documents. If the certificate is not uploaded, the system will not be able to build an installation package, and the app cannot be published.

• App certificate

  • Re-signing for Android: App security can be improved after setting. For more information, see Resignature Configuration.

  • App Signing Certificate: You can apply the certificate to specific services. For example, you must provide the certificate to get the token that enables Login with Amazon (LWA).

• Set the Push certificate according to the location of the app user:

  • Google FCM: the certificate information that must be set when you use the Google Push service. For more information, see Register the Firebase Cloud Messaging (FCM).

  • If you are pushing to users in mainland China, you can use the Tuya push channel or Umeng push channel.
    In addition, if you want users to receive pushes without the need to open the app, you need to set up the branded system-level channel to push certificate information.

Map for Android

Click Get SHA-1 to get the related values, follow the instructions in Apply for Google Map Key and Apply for AutoNavi Map KEY to get the Google Map key or AutoNavi key, and then enter the key in the corresponding box.

Third-Party login

App Store requires that both Apple login and third-party login must be enabled for the same apps. You can enable the third-party login in the Apple certificate.

• Users in mainland China can log in to your app with Tencent QQ and WeChat accounts.

• Users in other regions or countries can log in with Facebook, Google, or LINE accounts. If a user logs in with a Facebook account, a minimum activity level is required. If the minimum activity level is not reached, the authorization might be revoked and the user cannot log in to the app with a Facebook account. For more information, see Facebook Login Application.

  

Simultaneous logins on multiple devices

You can choose whether to enable simultaneous login to multiple mobile phones with the same account.

Common tools

QR code

The QR code can be printed on the outer packaging of the product and can be used properly even if the app is updated later. Make sure that the download address entered is available. The app details page of each app store is preferred.

Note: The QR code of one download address must be configured before the QR code can be displayed. You can get download links in the app stores. Only after the download link of each operating system is set, the mobile phones of the corresponding operating system can scan the QR code, and visit the download link to download the app.

Update notification

When a version update of your app has released, you can configure a push notification here and push the update to the user’s app. The user chooses whether to update or not. For more information, see Configure Upgrade Notification Push.

Debug whitelist

If your app uses the template version v3.20.0 or later, the setting bar will appear. You can add an app account in mainland China to the whitelist. Choose Me > Settings > Multilingual Debug Mode in your app. This allows you to check the latest updates of UI text. For more information, see What is the debug whitelist?

Multilingual settings

Currently, you can modify all entries in batch and modify specified entries online.

• Method 1 (batch modification): You can export the language content table of the app, modify the content in the table, and post the modification.

• Method 2 (individual modification): You can search for the specified entry through the app content and modify it.

  For more information, see App Multilingual Introduction.

Subscribe to template updates

The OEM app can be iterated and updated. After you enable the subscription function on the Subscribe page, when the template is updated, the system automatically sends the update notification to the specified email address.

Note: Currently, up to 30 email addresses can be set at the same time.
