Hi @mercadovirreyes05 We have a series on Youtube about using the Web API component: [![](https://img.youtube.com/vi/rUnWhwHHmO4/maxresdefault.jpg "Thunkable Web API Component [Snap to Place]") ](https://www.youtube.com/watch?v=rUnWhwHHmO4) There are also a few examples of POST requests here in the community. * * * > [@mercadovirreyes05](#): > > but i cannot called correctly. Can you tell us what error message or response code you’re seeing? ---

Thanks for your time and support. I tried to use the curl parameter in the web api headers and then in the parameters, and I don’t have any response, authorization error or just a “null”. I am really just experimenting because I don’t know even if the curl can be called in the that I tried to do it. Please any suggestions means a lot to me. My intention is generate a pdf file from a html code or html text. In advance, thank you, for your time. ---

You will probably want to create the PDF using the HTTP API? [https://pdfcrowd.com/doc/api/html-to-pdf/http/](https://pdfcrowd.com/doc/api/html-to-pdf/http/) I imagine here is where you might start (though I could be mistaken!) ![post-PDF-conversion-start](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/2/d2fc8acee3a25065f2c3751d5aef48206049cb6f.png) If you use `create object` it can create the json headers you need for the API to create the PDF. That link has most of what you need to complete it. _(ignore the button click component that’s just for the example)_ ---

Hi Eric, it make sense. I tried a different method by making a list. I am going to tried in the way that you suggest. And post here if it is the correct way. Thank you. ---

Authorization failed- Provide a valid username and API key. Is the error code that i get. But i dont have idea if what i am doing is remotely correct. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/b/1b3f1b2be3b12e57f7a6bd6f631450dcd577033f.png) ---

@mercadovirreyes05 The body shouldn’t be curl. You need to start with this: ![web-api-example](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/a/aa0910dbf7125aed30f3a2ac37bbaaaea10654a2.png) Put your correct API key in there and don’t add the colon ‘ **:** ’ after Authorization, it will do that for you when you click the **Add** button Then you can use these options in the create object component [https://pdfcrowd.com/doc/api/html-to-pdf/http/#reference](https://pdfcrowd.com/doc/api/html-to-pdf/http/#reference) like this: ![thunk-pdfcrowd-2](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/e/7ea513b04273c30d12d98c674011c9ffab6b1aaa.png) I don’t have a valid API key but that should return a URL which you can put in an “Open Link” Control Component 😊👍 ---
