# Wait for Form Submission

Wait for Form Submission parks the workflow until a chosen form receives an entry that matches your rules, or until the wait expires.

## When to use it

Use it for a second-stage form, a confirmation form, or any process where another submission must arrive before work continues.

## Settings

| Setting | What it does |
|---|---|
| **Form to wait for** | Selects the target form. Leave it empty to use the workflow's form. Accepts [flow tags](/documentation/flowcrafter/building/using-flow-tags/). |
| **Match rules** | Required rules identifying the expected submission. Match **all** or **any**. Expected values accept flow tags. |
| **Expiry** (hours) | Automatically takes **Expired** after this many hours. Defaults to `168` (seven days) and accepts flow tags. Values below `1` become one hour. |

Match values are resolved and frozen when the step parks, so later changes to earlier data do not alter what the run is waiting for.

## Branches and output

| Branch | When it runs |
|---|---|
| **Submitted** | A new entry on the target form matches the rules. |
| **Expired** | No matching entry arrives before expiry. |

On **Submitted**, output includes **Submitted entry ID**, **Submitted form ID**, and **Submitted at**.

## When Go To visits this step again

Each visit freezes its own match rules and expiry timer. A matching entry can satisfy this step only once per run; duplicate delivery of that entry cannot answer a later visit. Submit a new matching entry for the next visit. A delayed, previously unseen submission is matched against the wait active when its callback arrives.

## Good-to-knows

- At least one match rule is required; the step will not wait for any arbitrary submission.
- Matching resumes every parked run whose rules match that new entry, so use a unique value when only one run should resume.
- Wait steps are not allowed inside a [For Each](/documentation/flowcrafter/nodes/flow/for-each/) **Each item** branch.

## Example

Add a hidden **Run key** field to a **Follow-up details** form and enable dynamic population with the parameter name `run_key`. Include `run_key={{run.key}}` in the form link you send from the workflow.

In Wait for Form Submission, choose **Follow-up details** as **Form to Wait For**. Add a match rule: **Run key** **is** `{{run.key}}`, and leave expiry at `168` hours. Only a submission carrying that run's key takes **Submitted**.
