To access the Contacts API you will authenticate with an OAuth Bearer token. Request the scope contacts.readonly and include the token in the Authorization header for each request.
Establish a secure connection between Holded and the Contacts API by exchanging credentials, securing tokens, and refreshing access as needed.

Automatically create Holded contact records whenever a new contact is added via the GHL API to reduce manual entry.
Push tasks from GHL to Holded so teams stay in sync.
When notes are added in GHL, update the corresponding Holded contact’s notes.
Register your app and secure API keys, then request the necessary scope (contacts.readonly).
Use OAuth to authorize the app against the Contacts API and Holded, then run test calls to verify connectivity.
Define field mappings (name, email, phone, tasks) and enable live syncing between GHL and Holded.
Answer part 1: You authenticate using OAuth2 and include a Bearer token in the Authorization header. Request the scope ‘contacts.readonly’ to access read-only data such as contacts, tasks, notes, and appointments. Always protect your tokens and refresh them regularly. Answer part 2: Test calls in a sandbox environment or with a development key before going live to ensure mappings and permissions are correct.
Answer part 1: The required scopes include at minimum ‘contacts.readonly’ to read data. If you need to create or modify records, you will request ‘contacts.write’ or similar scopes as appropriate. Answer part 2: Review the permission scheme in your GHL developer console and ensure your app has access to the needed resources.
Answer part 1: Yes. You can create or update Holded contacts from GHL data by enabling the appropriate write permissions and implementing field mappings. Answer part 2: Use the POST /contacts/ and PUT /contacts/:contactId endpoints to synchronize records bidirectionally, respecting rate limits.
Answer part 1: Rate limits vary by plan. Start with the default sandbox limits and monitor responses for 429 status codes. Answer part 2: Implement exponential backoff and clear logging to handle throttling gracefully.
Answer part 1: Check endpoint responses, authentication headers, and field mappings. Look for error codes and messages in the API response. Answer part 2: Use test runs and ensure the data types match the target fields in Holded to prevent sync failures.
Answer part 1: No-code setup is possible with standard connectors and automations. You can map fields and configure triggers without writing code. Answer part 2: If you run into complex needs, consider a lightweight script or using a middleware tool to transform data.
Answer part 1: Endpoints and docs are typically available in the developer portal for the GHL Contacts API and the Holded integration. Answer part 2: Look for tutorials, endpoint references, and sample payloads to guide your setup.
