400
Publisher
Invalid Publisher Identity
HTTP 400 from OpenRTB 2.5 when the Publisher Identity is missing, contains characters other than letters, numbers, underscores, and hyphens, or is longer than 64 characters. The JSON error is "Invalid publisher key".
Cause
The {PublisherKey} path segment is missing, contains other characters, or is longer than 64 characters.
Solution
Replace {PublisherKey} with the Publisher Identity from your Account Manager. Do not leave the braces in the live URL. Do not treat HTTP 400 as a no-bid, and do not retry the same call unchanged.
Example
JSON
{
"error": "Invalid publisher key"
