Merge

Combine data from multiple branches back into a single output path.

When to Use the Merge Component?

Use the Merge component when you need to:

• Combine outputs from two or more previous steps

• Bring data back into one path after branches

• Append or merge lists into a single list for next steps

How to Configure the Merge Component?

Step 1: Add and Name the Merge Component

• Add the Merge component to your flow

• Give it a clear and descriptive name based on what you're merging (e.g., “MergeOutputandTokens”)

This helps in identifying the merged output in the next steps.

Example Use Case

You previously had:

• A Loop Over Webhooks step → produced a list

• A Slack – Generate Token step → produced token headers

After adding the Merge step, both outputs will be taken as inputs

• Strategy selected: Append

• The outputs are merged into one unified list

This lets you work with one combined result rather than handling two separate values.

When merging lists, ensure that both lists follow the same format. This ensures the merge works correctly, and you can map the merged data without issues

Step 2: Select the Input Lists to Merge

You will see fields to add the inputs you want to merge:

• Enter the reference for each list you want to merge e.g.:

  • {{steps.loopOverWebhooks.output}}

  • {{steps.generateToken.headers}}

Add or remove fields using the icons on the right, based on how many sources you are merging.

Step 3: Choose the Merge Strategy

You must select how the lists should be merged. For example:

• Append → Appends the lists in order, combining them into one list

This means list items from the second input will be added after the first list.

Step 4: Set the Number of Sources

• Specify the number of sources you are merging

Add or remove the source fields to match this count

Step 5: Add a Success Message to Display Output

Once your merge is complete:

• Add a Success Message component at the end of the flow

• Output the merged value inside this step

• Run the flow to confirm it executes successfully

This will allow you to view both merged values clearly in the final output of the flow.
