I am building a local application using Excel to post a message with a chart to StockTwits using the API. Since the file is local and API calls for this syntax to upload a Chart:
curl https://api.stocktwits.com/api/2/messages/create.json -F access_token=<access_token> -F body="Creating a new message with a chart. \$ticker" -F chart=@/path/to/a/local/image/file.jpg
My JASON body text looks as follows:
{"body":"Testing a post for $WDC with a chart testing two again to see if this works","chart":"file://C:/My_Folder/My_File.png"}
However when I POST this to the API I get the following error:
{"response":{"status":422},"errors":[{"message":"There was a problem with the URL. Please check to make sure the provided URL is valid"}]}
What is incorrect in my local file syntax?
