Short answer

How can my AI update ManyChat custom fields?

Your AI uses the ManyChat MCP to read subscriber profiles and write new values to specific custom fields. This keeps your contact data in sync with your conversations. You'll see how the agent handles these updates below.

Data outcomes

Where your data lands.

The AI routes information based on the specific field or subscriber you are targeting.

DATA

Updated profiles

The AI writes new values to your ManyChat custom fields. Your subscriber records stay current without manual entry.

AUDIT

Field lists

The AI checks your existing field structure. It knows which custom fields are available to be modified.

CONTEXT

Subscriber details

The AI pulls current data from specific users. This ensures it has the right context before making changes.

HUMAN

Manual review

If a field doesn't exist or a value is ambiguous, the AI stops. You decide how to fix those specific cases.

The workflow

What your AI does when <the thing arrives>.

The AI moves from reading your current setup to executing specific data changes.

  1. Identify the user

    The AI finds the specific subscriber you want to update by looking up their profile.

    get_subscriber

  2. Check field availability

    The AI looks through your ManyChat setup to see which custom fields are ready to receive data.

    list_custom_fields

  3. Apply the update

    The AI writes the new information directly into the chosen custom field for that subscriber.

    set_custom_field

  4. Verify the change

    The AI checks the subscriber's profile again to confirm the new value is active.

    get_subscriber
