Have a client who uses the API on a weekly basis for their sales activities. We do light usage of the API, not heavy traffic so we are not anywhere near rate limits etc.
Is it absolutely necessary to upgrade to v2 API?
Hi! Technically nothing’s broken yet if you’re staying well under rate limits, but v1 endpoints are being phased out over time, so you’d likely run into unexpected problems down the line as more of them lose support. Worth planning the migration to v2 now rather than waiting for something to break: Reminder: Deprecated API v1 endpoints are now out of support
