Get Multi-Partner Solution Access Token

Retrieve a granular BISU access token for accessing customer business resources through the Multi-Partner Solution. The token provides secure, scoped access to WhatsApp Business Accounts that have been shared with the solution.

Use Cases:

  • Obtain secure access tokens for partner applications to access customer business resources
  • Enable multi-tenant partner architectures with dedicated tokens per customer business
  • Support secure API operations on shared WhatsApp Business Accounts
  • Implement proper security boundaries between different customer businesses

Rate Limiting: Standard Graph API rate limits apply. Use appropriate retry logic with exponential backoff.

Token Management: Access tokens are time-limited and should be refreshed before expiration. Store tokens securely and implement proper token rotation strategies.
