What you see below is the list of error messages shown when API calls are rejected due to the sending limits mentioned in our API documentation. To prevent data loss, you’ll want to address the issues mentioned below as soon as possible whenever they come up.
These limits have been put in place to ensure the performance and reliability of your Customer.io account.
If you get these errors and do not fix your integration so that, for example, it only sends a maximum of 30 attributes per identify call and a maximum of 1000 bytes for attribute values, these types of requests will continue to fail.
If you have a use-case which needs these limits relaxed and it doesn’t interfere with our ability to provide the service, we can raise them on request. Please contact us so that we can discuss your use-case in detail.
