Got stuck with webhook error 400? We can help you in fixing it.

Webhooks facilitate syncing and relaying data between two applications.

At Bobcares, we often receive requests to fix webhook errors as a part of our Server Management Services.

Today, let’s have a look at this error, its causes, and some top fixes.

What is webhook error 400?

A webhook is a popular API concept. It is the way of exchanging real-time information between applications.

API and webhook perform similar functions but have some differences too. In the case of API, it delivers data when requested. But, webhooks get the data in realtime when the criteria are met.

Usually, we design an API for the webhook to use. Therefore, the chances for errors are more.

Webhook error 400 occurs due to the malformation of the request. Sometimes, the data sent by the client to the server have an incorrect format. And, this differs from the way the receiving service want the data to be.

Therefore, it returns error 400.

How we fix webhook error 400?

So far we have discussed the error. Let’s now see how our Support Engineers fix this error effectively.

1. Script errors

When we design API for webhooks, it is possible to have script errors.

Incorrect scripting is a major cause of error 400. So, it is important to double-check the scripts to avoid errors.

Recently, one of our customers approached us with a webhook error. He tried setting up the Stripe webhook for his app.

But, when he sends the test webhook from within Stripe, the following error returns.

“Test webhook error: 400”

Our Support Engineers checked this tricky error and found errors with the data provided. He made mistakes while setting up endpoints.

While setting up the endpoints, he accidentally chose the Connect option instead of Accounts.

Selecting the Accounts option resolved the error and then webhooks started working fine.

2. Special characters

Similarly, the appearance of special characters in the given credentials will also cause this error.

For instance, the appearance of ” in username can cause this error.

So, we double-check the data for avoiding such errors.
