Access Tokens Guide | Developer Documentation

Which credentials do you need for a ChatArchitect integration?

For a supported ChatArchitect WhatsApp integration, use the App key and Secret supplied for your connection. You do not need to create a Meta System User access token. ChatArchitect does not offer customers a workflow for calling Meta's Cloud API directly with their own token.

A Meta access token and a ChatArchitect App key are different credentials. Do not paste a Meta token into an App key, App ID, or Secret field in an integration setup form. If a guide asks for a Meta Bearer token or Graph API permissions, it describes a separate direct Meta API workflow, not the standard ChatArchitect connection.

Connect a tool or create a template

1. Connect your WhatsApp Business number with ChatArchitect. Obtain the credentials issued for that connection. If you have not received them, ask ChatArchitect support; do not generate a replacement token in Meta Business Settings.
2. Open the instructions for the tool you are connecting and enter the ChatArchitect credentials in that tool's integration form. Keep the key and Secret from the same connection together. Some tools use different labels for their credential fields, so follow that tool's setup guide.
3. For message templates, use the same connection's App key and Secret at wtargeted.com as described in the template creation guide.
4. Complete the integration's test message or template check before starting a campaign.

If the connection rejects your credentials

• Check that you copied both values completely and entered them in the intended fields. Remove accidental leading or trailing spaces.
• Confirm that the key and Secret belong to the WhatsApp connection selected in the tool. Do not mix credentials from different numbers or accounts.
• If the error continues, contact ChatArchitect support with the integration name, approximate time, and exact error text. Identify the connection without sending the full Secret in a message or screenshot. Ask support to check or reissue credentials if needed.

Meta's Cloud API documentation explains its own user and system user access tokens. Those instructions apply when building a direct Meta API integration outside the supported ChatArchitect workflow.
