Store the last updated date timestamp for each project

[adanielyan]

I have a use case when I need to download the translations from tolgee and store them locally in case there is no internet connection. Every time my the app launches I want to refresh the cached translations by downloading them from tolgee, in case they changed since the last caching. However, my project has a few thousand translation and downloading them takes time, especially for users with slow Internet connection.

Therefore I want to download translations only if they where changed. For that reason it would be great to have a project "updated" timestamp in the /v2/projects/{projectId}/stats API endpoint that will update every time a translation in that project is added, deleted, or updated.

Hi there! Thanks for reaching us! That's where ETAG header, comes into play. Just tell us which endpoint do you use for the export and we can add the support for it.

[adanielyan]

Thank you for a super quick response! This is the endpoint we use: /v2/projects/translations/{languages}.

[JanCizmar]

For /v2/projects/translations/{languages} there already is ETag header support implemented. So if you store the ETag and send it in each request, you'll get Not modified response, if the data didn't change.

[JanCizmar]

It cannot, because it's always related to the translations data. Sorry. But the server won't send the data if it wasn't modified after that time. But you can set the last modified header to the time on future, get Not Modified response containing the actual Last Modified value. That should work (I didn't test it, just checked the docs).

Thank you, Jan. One more question. What format should the value of If-Modified-Since header be? Is it a timestamp? I noticed that the Last-Modified header is sent in the response even when I don't provide the If-Modified-Since header in my request.

Last-Modified is the information the server is giving you about when the resource was last modified. You should keep this value somewhere, and send it back in the If-Modified-Since header. Similar to how ETag and If-None-Match work.

Thank you, Cynthia. The value of the Last-Modified is a formatted date string, e.g. Fri, 09 Jun 2023 15:49:52 GMT. Should I send that same formatted string in If-Modified-Since or should I send a timestamp, e.g. 1686423028?

[adanielyan]

OK, never mind, found my answer in the link you shared. Thanks again!

@JanCizmar does the Export Data Api also support If-Modified-Since header ? If no then what should I use ? if I want tolgee universal placeholders along with APPLE_STRINGS_STRINGSDICT format .

Hello, unfortunately the endpoint doesn't support this. However, you can use the content delivery (CDN), where this is supported.
