Hi Community! I am Getting a Response from Slazzer API as an Error even After Converting the file into base64. Please help. ![uoiuiouououio](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/f/7f57ea7181de296458a9aec5fc8246d0c2de4f21.png) ![oluiuluio](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/f/1fead3a984ad9b6f70098f615df76a0f47af2894.png) ---

You’re complicating things by adding a web viewer. Can you use a text block (string) as the value for the ~~source\_image\_file~~ \* property and take this out of the web viewer event block? When you do that, what error do you get? \*The documentation shows that the property you need to use with base64 strings is **source\_image\_base64**. ---

I know it can feel like we know the answer and we’re just not telling you. It’s not that! It’s that POST API calls are complicated, especially when adding a file. And it would take a while to set up and test all of this on our end, especially since we don’t have an API key to use. So we’re left providing suggestions but @muneer is right and if you check the link to the topic I provided, you should be able to piece together a test. And then post new screenshots or a link to your project and we’ll go from there. ---

> [@pacecode](#): > > Error again I van see two issues 1. You are using a block to get the URL of a file but the option says `source_image_base64` which is not the correct option. Also remember if you use the url option then it will not work with files from your computer or mobile device. You have to use a fully qualifies names such as url that starts with `http://`. 2. The body of the Web API is not a JSON object and you should not use `create object` or `generate JSON from object`. You should use the text style suggested by the API document. ---
