Inbound replies on WhatsApp
Let your AI agent reply automatically to messages customers send to your WhatsApp number.
When a customer messages your WhatsApp number, your AI agent can reply automatically. This takes a one-time setup on your Meta account so Meta forwards incoming messages to OmniDimension.
Before you start
- Your WhatsApp number is imported in OmniDimension.
- An agent is attached to the number. The agent's prompt and language decide how it replies.
Activate inbound replies
Right after you import a number, OmniDimension shows an "Activate replies" step. Pick one of the two methods.
Method 1: Connect automatically (recommended)
Paste your Meta app secret and we set everything up for you. Find it in the Meta App Dashboard under App settings, then Basic.
Method 2: Set it up yourself
Prefer not to share your app secret? In the Meta App Dashboard, open WhatsApp, then Configuration:
- Next to Webhook, click Edit. Paste the Callback URL and Verify token shown in OmniDimension, then click Verify and save.
- Next to Webhook fields, click Manage. In the popup that appears, subscribe to the messages field, then click Done.
Meta verifies the callback the moment you click Verify and save. Once it is verified and messages is subscribed, replies start working.
Subscribing to the messages field is required. Setting the callback URL on its own will not deliver any messages, this is the step people miss most often.
Good to know
- Replies use the agent attached to the number. Change how it answers by editing that agent's prompt and language.
- The reply is sent from your own WhatsApp number through your Meta account.
- Image and other media messages are handled separately, and support for them is expanding.
