When to use this node #

Search the web with OpenAI and return cited answers.

Add OpenAI Web Search to a workflow branch using the node picker. Configure its fields in the inspector, then connect the next step.

Before you begin #

Connect OpenAI in App Connections first. Select the intended account in this node; an account connected to a different service is not interchangeable. Available actions depend on the permissions granted to that connection.

Configure the fields #

Field	What to enter
OpenAI Account	Select the OpenAI connection to use for this node.
Model	OpenAI models verified for this capability. GPT-5.2 is omitted from search tools pending confirmed support. Choices: `gpt-6-astra`, `gpt-6.1-sol`, `gpt-6-sol`, `gpt-6-luna`, `gpt-5.6-sol`, `gpt-5.6-terra`, `gpt-5.6-luna`, `gpt-5.5`, `gpt-5.4`, `gpt-5.4-mini`. Example/default shown in the editor: `gpt-6.1-sol`.
Instructions	Optional instructions for the model.
User Content	The prompt or query to send to OpenAI.
Reasoning Effort	max requires GPT-6 or GPT-5.6. Custom none is accepted except by GPT-6 Astra / GPT-6.1 Sol; Web Search requires reasoning. Choices: `low`, `medium`, `high`, `xhigh`, `max`. Example/default shown in the editor: `medium`.
Search Context Size	Optional search context size. Choices: `low`, `medium`, `high`.
Allowed Domains	Optional comma-separated or newline-separated domains, without URL schemes or paths (up to 100).

Use the result #

Choose the output from the variable picker in a later step. Output names below identify the values supplied by this node; the picker inserts the correct reference for your node instance.

Output	Meaning / label
`response`	response
`responseId`	responseId
`model`	model
`error`	error
`citations`	citations
`searchResults`	searchResults

Connect the next step #

This definition exposes these paths:

Success — branch 1.
Error — branch 2.

Connect each relevant outcome, especially any error or timeout path. Outputs can differ by outcome; check that a result exists before using it.

Test it in a workflow #

Configure this node with a small, recognizable test input or a test resource.
Check the variables from preceding steps and the connection selected in the inspector.
Save the workflow. For event-driven flows, generate the actual event; use Run only for a Manual workflow.
Open Workflow Activity and check the outcome before enabling wider use.

AI processing can use your connected provider account and incur charges. Choose an available model in the current selector and test with a small input. Handle provider errors and unavailable results explicitly.

If something goes wrong #

Reconnect the account if authorization has expired, then verify its permissions on the specific resource.
Check empty variables, selected resource IDs, and any fields that appeared after resource selection.
Check the failed step in Workflow Activity before retrying. If the action may already have completed, inspect the destination first to avoid duplicates.
Follow the troubleshooting guide for a symptom-by-symptom checklist.

Catalog coverage #

This is the currently documented selection. Chatigram continues to add nodes, triggers, App Connections, and integrations. Use each page’s review date and the current application selectors to check what is available now; this catalog is not a fixed limit on future features.
