Removal of HTTP reason phrase

Beginning March 1, 2023, the Bandwidth Dashboard API will no longer guarantee that the HTTP reason phrase will be sent on responses to API requests. This is in accordance with the HTTP standard (RFC 9110, Section 15.1).

This change means that a response that used to look like this:

GET https://dashboard.bandwidth.com/api/tns?npa=919

HTTP/1.1 200 OK

 

Will now return this:

GET https://dashboard.bandwidth.com/api/tns?npa=919

HTTP/1.1 200 

 

Please verify that your apps do not use the reason phrase when processing responses from our API in advance of March 1.

New file type restrictions

In order to improve security and reliability, we are limiting the types of file uploads we support for both port-in documents and import TN documents. We are also adding validation to ensure that the content-type header, the file type extension, and the MIME-type are consistent with each other.

  • CSV (“text/csv”)
  • DOC (“application/msword”)
  • DOCX (“application/vnd.openxmlformats-officedocument.wordprocessingml.document”)
  • JPG/JPEG (“image/jpeg”)
  • PDF (“application/pdf”)
  • PNG (“image/png”)
  • TXT (“text/plain”)
  • TIFF (“image/tiff”)
  • XLS (“application/vnd.ms-excel”)
  • XLSX (“application/vnd.openxmlformats-officedocument.spreadsheetml.sheet”)

If you have any questions regarding this upcoming change, reach out to your Bandwidth Support Team!
