Question Third Party DNS TTL Input Parameter

[HExSM]

I use a custom extension to update our nameserver. Yesterday we switched from Plesk Onyx to Plesk Obsidian. Since Plesk Obsidian 18.0.31 it is possible to enter the TTL for a resource record.

Now I want to update my custom extension and get the value from the zone data instead of a static value. At Third-Party DNS Services I found the list with the available parameters. Unfortunately I can't find the value for TTL. I guessed it's zone->rr->ttl, but that didn't work.

Can someone tell me how to get the TTL value for a resource record?

Thank you in advance!

Unfortunately I don't know the direct answer to your question. However, the Plesk Route 53 extensions seems to support TTL synchronization. The extensions code is available on GitHub. Perhaps you could search trough the code extension to see how this is achieved?

Also TTL is actually mentioned in the Third-Party DNS Services documentation. From the looks of it I would guess it would something like zone->name->ttl.

Coincidentally I have been playing with the Plesk REST API today to get DNS zones. I noticed that the TTL values are only shown in the API results when an record has a different value set by a user. Perhaps this is the case as well for retrieving DNS zone data for an extension. So zone->rr->ttl (or any other variety) might not return anything if no TTL value has been set for a record.

However this is just speculation on my part, based on my observations with the REST API today.

Hi @Rasp ,
thank you very much for your hints!

I analyzed the Route 53 extension, but there zone->soa->ttl is used for all records. It does not use the new TTL field for the resource records, which was added in Plesk Obsidian.

But your speculations about zone->rr->ttl and that it's only filled if it's not the default value looks promising. I will give that a try.
