How to update a multi-value linked field from my Zap?

I have a Members table in Zapier with a linked field to another table let’s call it Interests for the sake of simplicity. On a Google form they select their interests and I would like it to populate this field with all of their interests. 

 

I’ve got the member record retrieved, all I have the interests by name in the values of a Line Item (the keys _0 _1 _2 etc)  but I can’t figure out how to update the multi-value linked field in the Members table. I tried passing them as a comma-separated list but it always fails with a validation error. 

 

I can’t find anything in the documentation about how to do this. Can someone please advise?

 

Thanks!

Thank you ​@Troy Tessalone I got it working. Oddly enough I was able to pas a list of comma-delimited labels that I had constructed in a previous step, and now it worked!

​@Troy Tessalone thank you for the reply. I looked at those links again (I had already visited them before).

The last one is the most relevant as it says how to update a linked record, however it doesn’t say how to update a multi-value linked record. 

Can you help with this? Maybe the documentation needs to be improved?

 

Thank you

​@jehsom 

Give this a try…

NOTE: A comma delimited text string is not an array of items.

Make sure the data is structured as an array of items.

You may need to use this Zap action: Formatter > Utilities > Text to Line Items

Formatter help: https://zapier.com/apps/formatter/integrations#help

 

Maybe the documentation needs to be improved?

I do not work for Zapier, so you’ll have to open a ticket with Zapier Support to share feedback: https://zapier.com/app/get-help

Glad you got it sorted ​@jehsom! And thanks for helping out here ​@Troy Tessalone 🤗

Would definitely be good to have some documentation in added to explain how to update Linked Record fields that can have multiple values, so I’ve put in an internal request to have the existing documentation on linked records updated.

Please do reach back out if there's anything else we can help with.
