Update API Endpoint

Here is an example of code in JavaScript to send an update to the plugin

interface AppInfos {
  version_name: string
  version_build: string
  version_os: string
  custom_id?: string
  is_prod?: boolean
  is_emulator?: boolean
  plugin_version: string
  platform: string
  app_id: string
  device_id: string
}

export const handler: Handler = async (event) => {
  const body = JSON.parse(event.body || '{}') as AppInfos
  const {
    platform,
    app_id,
    version_os,
    device_id,
    version_name,
    version_build,
    plugin_version,
  } = body
  console.log('update asked', platform,
    app_id,
    version_os,
    device_id,
    version_name,
    version_build,
    plugin_version)
  if (version_name === '1.0.0') {
    return {
      version: '1.0.1',
      url: 'https://apiurl.com/mybuild_101.zip',
      checksum: 'sha256_checksum_of_bundle',
    }
  }
  else if (version_name === '1.0.1') {
    return {
      version: '1.0.2',
      url: 'https://apiurl.com/mybuild_102.zip',
      checksum: 'sha256_checksum_of_bundle',
    }
  }
  else {
    return {
      message: 'Error version not found'
      version: '',
      url: '',
    }
  }
}

Response Format

For non-encrypted bundles, your endpoint should return:

{
  "version": "1.0.2",
  "url": "https://apiurl.com/mybuild_102.zip",
  "checksum": "sha256_checksum_of_bundle"
}

For encrypted bundles, you also need to include the session key:

{
  "version": "1.0.2",
  "url": "https://apiurl.com/mybuild_102.zip",
  "checksum": "encrypted_checksum_from_encrypt_command",
  "session_key": "ivSessionKey_from_encrypt_command"
}

And if no update or error, add the message key and optionally an error:

{
  "message": "Version not found",
  "error": "The backend crashed",
  "version": "1.0.2",
}

Field Descriptions

• checksum: SHA256 hash of your bundle zip file for integrity verification
• session_key: Required only for encrypted bundles - this is the ivSessionKey returned by the encrypt command
• version: Version identifier in semver format
• url: HTTPS URL where the bundle can be downloaded

Bundle Creation

To learn how to create compatible bundles and generate checksums, see the Auto Update documentation.

For encrypted bundles, see the Encrypted Bundles documentation which explains the complete encryption workflow.
