AI Ability since v2.0.0

# assign\_credential

Assign a vault credential to a webhook — Reference a stored vault credential from a webhook by id (the secret is injected at dispatch time and never exposed).

Reference a stored vault credential from a webhook by id (the secret is injected at dispatch time and never exposed). Registered as the WordPress Ability `flowsystems-webhook-actions/assign_credential`, so external AI tools (Claude Code, Cursor) can call it over MCP or REST with a scoped API token.

/ Plan step shape

```
{ "ability": "assign_credential", "input": { "webhook_id": …, "credential_id": … } }
```

/ Scope & confirmation

Minimum API-token scope for external (MCP/REST) callers: `full`. Runs without a confirmation pause (the overall plan is still user-approved before execution starts).

/ Input fields

| Name | In | Type | Req | Description |
| --- | --- | --- | --- | --- |
| webhook\_id | param | integer | yes |  |
| credential\_id | param | integer,null | — |  |

/ Examples

Plan step as the AI Builder proposes it

  "ability": "assign_credential",
  "summary": "…",
  "input": {
    "webhook_id": 12,
    "credential_id": 3
  }
}
```
