Add a comment to a customer invoice. The comment appears in the
Comments section of the invoice in Pennylane, authored by the user
who granted the access token. Access tokens that are not issued to a
user are rejected with a 403.
The content is stored as plain text. Mentions and rich text are not
supported. A content made only of Unicode whitespace, such as no-break
spaces, is rejected with a 422.
This request is not idempotent: each call adds a new comment, so
retrying after a timeout can create a duplicate.
This endpoint requires the following scope:
customer_invoices:all
| Time | Status | User Agent | |

414URI Too Long: the request URL exceeds the maximum length. Shorten the query string, for example by sending fewer values per query parameter and splitting them across several requests.
