Append New Collections to an Array in Iterator

[Ajay]

Hi everyone,

I am processing a payload received from a webhook, which contains an array of collections. I am using an Iterator to loop through each collection and perform some transformations. However, I need to:

1. Extract and modify data from each iteration (which I am doing successfully).
2. Combine each processed bundle into a new collection.
3. Append each new collection to an array that stores all modified bundles.
4. After all iterations are done, map this array to a new json payload.

Current Setup:

• Webhook → Receives payload
• Iterator → Loops through an array in the payload
• Set Multiple Variables → Extracts & transforms data

Problem:

Right now, the process runs per iteration, and I am unable to collect all processed bundles into a single array. The workflow is getting stuck at Webhook → Iterator → Set Multiple Variables, and I don’t know how to store all iterations together before moving forward.

What I Need:

• How can I store and append each processed collection into an array?
• How can I ensure the process only continues after all iterations are done?
• Do I need an Array Aggregator or another module to achieve this?

Thanks in advance!

Welcome to the Make community!

There is probably more than one way to do what you want, but which is used depends on your use-case.

If you need further assistance, please provide the following:

1. Relevant Screenshots

Could you please share screenshots of your full scenario? Also include screenshots of any error messages, module settings (fields), relevant filter settings (conditions), and module output bundles. We need to see what you’re working with to give you the best advice.

You can upload images here using the Upload icon in the text editor:

2. Scenario Blueprint

Please export the scenario blueprint. Providing your scenario blueprint file will allow others to quickly recreate and see how you have set up the mappings in each module, and also allows us take screenshots or provide module exports of any solutions we have for you in return - this would greatly benefit you in implementing our suggestions as you can simply paste module exports back into your scenario editor!

To export your scenario blueprint, click the three dots at the bottom of the editor then choose ‘Export Blueprint’.

You can upload the file here by clicking on this button:

3. Output Bundles of Modules

Please provide the output bundles of each of the relevant modules by running the scenario (you can also get this without re-running your scenario from the History tab).

Click on the white speech bubbles on the top-right of each module and select “Download input/output bundles”.

A. Upload as a Text File

Save each bundle contents in a plain text editor (without formatting) as a bundle.txt file.

You can upload the file here by clicking on this button:

B. Insert as Formatted Code Block

If you are unable to upload files on this forum, alternatively you can paste the formatted bundles.
These are the two ways to format text so that it won’t be modified by the forum:

• Method 1: Type code block manually

  Add three backticks ``` before and after the content/bundle, like this:

  ```
  <sup>content goes here</sup>
  ```

• Method 2. Highlight and click the format button in the editor

  

Providing the input/output bundles will allow others to replicate what is going on in the scenario, especially if there are complex data structures (nested arrays and collections) or if external services are involved.

Sharing these details will make it easier for others to assist you.
