The `web API` component has more than one option as seen in the image ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/3/6/36c77230048f8c422d2d10aef8ecb0373e53645d.png) You need to select the option that is required by the service you intend to use and supply necessary details. For more explanation you need to give details of what you are trying to do. ---

This is a general explanation and can be used as general guideline. Every API has a strict and definite requirement that has to be meet to get the result from it. The example here is to obtain a signature string required by another API ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/c/5/c5658d9ed3e705b2b2e10436131d88970250d9f0.png) This is a `POST API` that would take the inputs supplied and use it to generate an outcome which is an encrypted key. It is hard to say anything else because every API is different. ---

> [@maheshrdd7j4vo](#): > > I am checking running code thunkable website Can you test on a device to see if that makes a difference? Do you have any blocks for error handling in your project? For example, what status is being returned? Finally, what API are you trying to connect to? Are you able to connect with something like Postman? ---

> [@maheshrdd7j4vo](#): > > Hi , can you send , which error your getting . If i now that error , I will help you. I’m very confused by your posting @maheshrdd7j4vo - we’re not seeing any errors. You need to include screenshots of your blocks, some details of the API you are trying to connect to and, yes, any errors that you are seeing otherwise we can’t really do anything to help you here. Thanks, Domhnall ---

Authorization issues. Either for access to the site in general or the access to service. With the little information you provide it is very difficult to help ---
