Does anyone know if you can do a CSV (or other format) import into Celigo (integrator.io) for static field mappings? Boomi allows this and it's quite nice to not not have to enter 300 static mappings via hand. An example of static mapping would be mapping salesforce account IDs to NetSuite account IDs.

Don’t believe so.

Not a current way with csv, but you could update the import resource via api. We are working to bring some global cache storage next year.

There is a great Chrome extension called ZangaBox that makes this really simple. You can just edit the existing flow and paste in all your mappings, then click "Put" to update the flow. That being said, typically for this type of mapping I would store an External ID in one of the systems

@michoel that extension looks amazing.
