Bitly returns with MISSING_ARG_LOGIN when I try to shorten my link

Question

I am trying to shorten my link with the following using post man:

http://api.bitly.com/v3/shorten?callback=?login=xxxxxx&apiKey=xxxxxx4a58968824c71e281208&longUrl=http%3A%2F%2Fbetaworks.com%2F&format=json

When I run the above I get the following:

{
"status_code": 500,
"status_txt": "MISSING_ARG_LOGIN",
"data": []
}

But based on what I see here:

I do not think anything is missing. Any idea?

Replace the last question mark with ampersand:

http://api.bitly.com/v3/shorten?callback=&login=xxxxxx&apiKey=...

I had the same problem with c# (httpclient). Response code was 200 but response content contains missing_arg_login

In my case, bitly api needs a trailing slash for baseadress

Fails

BaseAddress = new Uri("https://api-ssl.bitly.com/v4")

Works

BaseAddress = new Uri("https://api-ssl.bitly.com/v4/")

With API V4 the schema has changed. You must send your generic token as a bearer in the header. EG Authorization: Bearer token

This endpoint has also changed to a post. Essentially it will look like this

https://api-ssl.bitly.com/v4 Headers Authorization: Bearer xyz Body: {long_url = "xyz"}

Their documentation is a little lacking. No where could I find how you were supposed to send the generic token.

Feel free to check out this link on how to use Bitly V4, It explains where and how to send the generic token. https://stackoverflow.com/questions/59431374/bitly-api-how-to-generate-oauth2-token-to-integrate-with-bitly-api-v4-and-make/59431375#59431375 – Andrew Reese Dec 30 '19 at 16:48

I had this same error and by simply opening a tab in POSTMAN and creating a new request with the Header information fixed it.

If anyone ever has any trouble generating an OAuth token in version 4 of Bitly please refer to this step-by-step guide I posted.
