Connect ChatGPT to Reyda so you can ask about your opportunities, documents, pipeline and buyers in a ChatGPT chat. You start in Reyda to get the exact settings, create the app in ChatGPT, then approve access back in Reyda. ## Before you start * You need an active account in your Reyda organization. Any role can connect, including Viewer. * Check the ChatGPT and Reyda plan requirements. See [Plan requirements](https://reyda.mintlify.site/integrations/mcp/overview.md#plan-requirements). > [!WARNING] > > Never paste your Reyda password or a dashboard token into ChatGPT's settings. You only sign in to Reyda on Reyda's own page, when ChatGPT sends you there. ## Get the settings from Reyda **1. Go to **Settings → Integrations** and open the **AI assistants** tab** You see a card for ChatGPT and one for Claude. If the tab isn't there, AI assistants aren't enabled for your Reyda environment. **2. Click **Connect ChatGPT**** The guide shows the **MCP server URL**, **Read scopes (if requested)**, **OAuth client ID** and **Registered callback URL**, each with **Copy**. If it says ChatGPT is not configured for this Reyda environment yet, email [support@reyda.ai](mailto:support@reyda.ai) before continuing. **3. Click **Open ChatGPT**** ChatGPT opens in a new tab. Keep the guide open in Reyda. ![Connect ChatGPT guide in Reyda showing the MCP server URL, read scopes, OAuth client ID and registered callback URL](https://mintcdn.com/reyda/-49LGMDX5S1iB5Lh/images/mcp/guided-setup-chatgpt.png?fit=max\&auto=format\&n=-49LGMDX5S1iB5Lh\&q=85\&s=a4da84e429e9f7a1298db21f4e5722d0) The guided setup for ChatGPT, with the server URL and copy buttons ## Create the app in ChatGPT **1. In ChatGPT, go to **Settings → Apps**** If Reyda is already available in your workspace, select it, choose **Connect** and skip to the next section. **2. Otherwise, create a custom MCP app in developer mode** If you can't create an app, check your ChatGPT plan and workspace permissions. **3. Name the app and add the server URL** Name the app Reyda and paste the **MCP server URL** from Reyda's guide. Choose OAuth. Enter the **OAuth client ID** and the read scopes from the guide if asked. **4. Check the callback URL** The callback URL ChatGPT shows must exactly match the **Registered callback URL** in Reyda's guide. Check this before you scan tools. **5. Scan the tools and finish creating the app** ChatGPT sends you to Reyda to approve access. ## Approve access in Reyda Approving here is what creates the connection; creating the app in ChatGPT alone doesn't. On **Connect your AI assistant**, you see your account (**Signed in as**), the **Organization** ChatGPT will read from, the site you **Return to** (such as chatgpt.com) and the four read permissions you grant together. ![Connect your AI assistant screen showing the signed-in account, organization, environment, return site and read permissions, with Allow read access and Deny buttons](https://mintcdn.com/reyda/-49LGMDX5S1iB5Lh/images/mcp/consent-screen.png?fit=max\&auto=format\&n=-49LGMDX5S1iB5Lh\&q=85\&s=9203f525f810d136cc8ae9af7ccac538) The consent screen in Reyda **1. Sign in to Reyda if asked** **2. Check the **Organization** and **Return to** site** Make sure they are what you expect before you approve. **3. Click **Allow read access**** Or click **Deny** to refuse. You return to ChatGPT. **4. Back in Reyda's guide, click **Check connection**** When Reyda finds your connection, the ChatGPT card shows **Connected** and a notice confirms it. > [!TIP] > > In a business workspace, the administrator publishes the app for members. Each member then connects their own Reyda account and approves their own access. ## Use Reyda in a chat Select Reyda from the apps or tools menu in your chat, then ask a question.

Reyda only accepts callbacks it has registered exactly. > [accordion] The guide says the app needs a client secret > > Some clients need an OAuth client secret. A workspace administrator configures it in ChatGPT. Reyda never shows the secret in the guide. > [accordion] I see "This connection request is unavailable or expired" > > Requests expire after a few minutes and can be used once.
