How to connect Contacts API with Relatel

This guide walks you through connecting Relatel to the Contacts API, highlighting authentication, available endpoints, and practical use cases for syncing contact data between Relatel and GHL.

Authentication for Contacts API

Authenticate requests using your GHL API credentials with the scope set to contacts.readonly. Include your API token in the Authorization header as a Bearer token to securely access contact data.

Authentication for Relatel

Configure Relatel to securely access the Contacts API by using OAuth 2.0 or API keys, granting only the readonly scope to protect data while enabling necessary access.

FAQ

What authentication is required for the Contacts API?

Authentication typically uses OAuth 2.0 or API keys. For read-only access you’ll configure the scope to contacts.readonly and include a Bearer token in your requests. If your use case requires updates, you may use the relevant write permissions (contacts.write) with secure storage of credentials. Always follow best practices for credential management and rotate keys regularly.

Read-only endpoints return data without requiring modification operations. Examples include fetching contacts, tasks, notes, and appointments. If you need to create, update, or delete resources, you must request and configure write permissions and ensure that your app enforces proper access control.

Yes. If your Relatel integration requires creating or updating contacts, tasks, notes, or appointments in the Contacts API, you will use write permissions (contacts.write) and the appropriate POST, PUT, or DELETE operations. Make sure to validate data before sending and handle conflicts gracefully.

Rate limits vary by endpoint and auth method. When designing your workflow, implement exponential backoff and proper error handling to retry failed requests. Monitor quotas within your GHL and Relatel accounts and adjust batch sizes as needed.

Field mapping is typically done in your integration configuration. Align core fields like email, firstName, lastName, and phone between Relatel and the Contacts API. Create mapping rules for notes, tasks, and appointments to ensure data consistency across systems.

No-code options are available via the Zapier App Connector, which lets you connect Relatel and the Contacts API without writing code. For complex workflows, you may add lightweight scripting or use a middleware platform if needed.

Data sync status can be monitored through logs and dashboards in the integration app. Look for sync status, error messages, and retry counts. Set up alerts to be notified of failures and verify data integrity after each run.
