# Unsupported Post Request Error in DoubleTick
If you see a **red error message** inside a customer chat in DoubleTick that says something like **“Unsupported post request”**, this article will help you understand **why this happens** and **what you need to do next**. *** ### What is this error? This error appears when DoubleTick is unable to complete a request with **Meta (WhatsApp Business API)**. In simple words: * Your WhatsApp Business API number is active * But the **server or BSP (Business Service Provider) setup needs an upgrade** * Because of this, Meta blocks certain requests and shows this error in the chat ⚠️ This is **not caused by anything you typed or clicked** in the chat. *** ### Why does this error occur? This usually happens when: * Your account is running on an **older server configuration** * The current **BSP or server setup no longer supports certain actions** To fix this permanently, the account needs a **server and BSP upgrade**, which can only be handled by the DoubleTick team. *** ### What should you do when you face this error? #### Step 1: Take a screenshot Take a **clear screenshot of the chat** where: * The red error message is visible * The customer conversation can be identified (The screenshot shown above is an example of what we need.) *** #### Step 2: Send the screenshot to DoubleTick Support Share the screenshot on our **official support WhatsApp number**: 📞 **+91 83568 49474** While messaging, briefly mention: * That you are facing an **Unsupported Post Request error** * That it is appearing inside the chat *** #### Step 3: A 15-minute support call will be scheduled Once our team receives your message: * We will review the issue * A **15-minute call** will be scheduled with you * During this call, our team will upgrade the **server and BSP configuration** This upgrade resolves the issue permanently. *** ### What you need to be ready with before the call To ensure the fix is completed in one go, please keep the following ready: 1. **Logged into your DoubleTick account** * With **Owner access** 2. **Logged into your Facebook Business Manager (FBM) account** * The FBM linked to your WhatsApp API 3. **Your API phone number available on a device** * You may receive an **OTP** during the process *** ### Will this error happen again?
