Hello Hrk,
The error message you’re seeing suggests that you’ve reached the maximum number of tokens or rate limit allowed by your current Ubidots plan. If you need more tokens or a higher rate limit than your current plan allows, consider upgrading to a higher tier plan. The Industrial license and above offer custom API rate limits.
Please take a moment to explore the following link to learn more about our Plans. Ubidots pricing — View our features and flexible plans
Note: Remember, when creating a new token, the rate limit option will be greyed out if you’re on a plan that doesn’t support custom rate limits. In such cases, tokens will have a fixed rate limit (for example, 4 requests per second for device tokens).
Best regards,
–Alejandro
