Workfront Custom API Module performance vs. native Workfront Modules

Does anyone know if there are any guidelines or documentation on when to use Workfront Custom API modules vs the Workfront Native modules (Create a record, Search, etc.) in terms of performance (execution time, throughput, impact on scenario performance, etc.)?

 

I typically default to using the Workfront Custom API modules due to familiarity but am curious if there are situations where native modules may perform better than the Custom API ones.

Overall depends on the following (for me);

  • Will I also be maintaining this solution?
    • If not, are the people that will maintain the solution also comfortable with Custom API calls?
  • Can we achieve what we're doing with the native modules?
    • Is it an unsupported action?
    • Are we creating/updating many records at a time (definitely better to use Custom API calls in that case and build a pattern that will impact up to 100 records per API call)?
  • How large is the system?
    • When working in Fusion it takes a few seconds - sometimes a bit more than that - longer to load native modules like Search or Create, and this can be longer if there's more to load ie thousands of custom forms to select from: the Custom API call module will always load in a couple of seconds or so

Also typically default to Custom API calls but it's a double-edged sword; you can build using patterns that aren't achievable with the native modules, but you need to get your hands dirty and transfer of maintenance can be a bit trickier depending on comfort levels.

 

Native modules are more user-friendly and sometimes though it looks like one simple action it's actually performing 2-3 different api calls in the background (take the Convert to Project action as an example, or Download Document).

 

Will it impact performance using native modules? Not really. Might just take longer to open those when making edits as it has to retrieve more information to show you than the custom API call modules.

Hi @ktomoz,

 

I have never done an analysis on this but I did not notice any difference between performance when it comes to, for example editing documents/issues between built in and custom API modules. Though I would still advice for usage of native modules as any possible change in the API structure will be reflected and you will not need to change multiple modules if for example something changes for a specific endpoint.

 

Hopefully this was helpful, if you need anything else please reach out to me.

 

Best regards,
