On April 13th, 2021, we will change length and format of the short-term access tokens used by addons as well as tokens generated for private API access (Premium eshops). The token length will be variable 38-50 characters. In addition to current character set (a-z, 0-9) there will additionally be a dash (-) as well.
For addons we assume there should be no impact, just the token will be shorter.
For private API tokens (Premium), the token will be longer, so you might possibly need to alter your database and eventually variable length, if limited. We will not change the existing tokens, but the new ones will be already generated in the new format.
Please check your software and adapt your software to support the new format until April 13th, 2021.
