Trigger to export priorities using Zapier

I am new to Zapier and I have a conceptional question about it.

I am building a prioritization tool and want to export the list of priorities to other project management tools and todo lists, like trello, asana, monday, etc., using Zapier.

When I create a trigger, should its form be done:

for a single task including its sorting order, or
for a project with the whole prioritized list of tasks using Line Item Groups?

My goal is to export tasks as separate trello cards, tasks on asana, etc.

Solution

I talked to Zapier support and the answer was, that normally, you export items from one app to another one-by-one, although it is also possible to use Line Item Groups and loops at Zapier with a paid tier.

There is one gotcha, that items are transferred from one app to another in parallel, so the sorting order can be guaranteed. But one thing that can ensure their order in most cases is providing the items incrementally at regular 1-minute intervals. Also, I include the priority index in the title for clarification, e.g.: "1. Fix the bugs".

You can find more technical details of the implementation at my blog post.
