A customer bought from our website in DecemberTranslatePress Translation PluginWhen discussing the free API with me, he told me that he was charged for using Google Translate API beyond the limit before, and sent me the following picture ↓. Because I forgot to set the limit and consumption reminder, I didn't know about the overage until I was charged $58 😆 .

Another visitor feedback he was deducted over $100 Google Translate costs ↓.



It is very necessary to set translation quota and overrun reminder, follow the steps below to set translation quota. Note: Setting quota can only limit the amount of characters to be translated per day at most, you can't set a monthly quota, and after exceeding the quota, it will be translated automatically the next day, which is actually rather useless. Setting consumption reminder is the most useful.

  1. Hello, I am a new Google user and I am setting up a google translate API! I'm a new Google user and I'm setting up the google translate API. how do I set the quota so that I can keep my budget within the gifted amount of USD300? The tutorial doesn't say exactly how many characters to set, and is it just v2 v3 general model per day? Thanks a lot for the reply!

    1. USD300, if your website has less than 1000 pages, you can't use it all. Setting up quotas is more complicated than the price, we suggest you set up a consumption reminder on the line, set up a consumption of more than 1 U.S. dollar to notify you - the most important thing is to measure their own translation of the site probably use the number of characters, good control.
