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?

No.\
Once the server and BSP upgrade is completed, this issue **will not reoccur** on your account.

***

### Summary

* This error is **backend-related**, not a user mistake
* It requires a **server and BSP upgrade**
* Share a **chat screenshot** on WhatsApp support
* Attend a **15-minute call** with the required access
* Issue gets **permanently resolved**

If you ever see this error, follow the steps above and our support team will take care of the rest.
