Question

I'm trying to insert a YouTube player on the page. I use the API telegra.ph/api. Tell me, please, where is my error?

Answer 1

Here is an example:

https://api.telegra.ph/createPage?access_token=b968da509bb76866c35425099bc0989a5ec3b32997d55286c657e6994bbb&title=Sample+Page&author_name=Anonymous&content=[{"tag":"figure","children":[{"tag":"iframe","attrs":{"src":"/embed/youtube?url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DtrHMLJpxG7o"}}]}]&return_content=true

so, the part after /embed/youtube?url= should be used with encodeURIComponent function . Also, figure tag is mandataory as I understand
