What to do if your operation isn't supported#

If this node doesn't support the operation you want to do, you can use the HTTP Request node to call the service's API.

You can use the credential you created for this service in the HTTP Request node:

  1. In the HTTP Request node, select Authentication > Predefined Credential Type.
  2. Select the service you want to connect to.
  3. Select your credential.

Refer to Custom API operations for more information.

Using tools with OpenAI assistants#

Some operations allow you to connect tools. Tools act like addons that your AI can use to access extra context or resources.

Select the Tools connector to browse the available tools and add them.

Once you add a tool connection, the OpenAI node becomes a root node, allowing it to form a cluster node with the tools sub-nodes. See Node types for more information on cluster nodes and root nodes.
