Catch Missed WhatsApp Promises After Closing a Chat

A customer asks: “Can you send me a quote in this chat?”

Your team replies: “Yes, I’ll send it here now.” The quote never appears, but the conversation is marked as resolved.

That is the kind of quiet mistake this Wassenger Flow looks for. When a team member resolves a one-to-one WhatsApp chat, an AI agent reads the recent conversation, checks your review criteria and decides whether the closure needs human attention. If the evidence is clear, the Flow adds a private note and the label Revisar cierre IA. It sends nothing to the customer.

We tested that exact scenario in Wassenger. The Flow found the unfulfilled promise, cited the two messages that proved it, created the internal note and added the review label. The final result reported customerMessagesSent: 0.

This gives a business owner or support manager a practical review queue. A person still decides what to do next, but they no longer need to reopen every resolved conversation to find the few that deserve attention.

What the Flow does

The reusable workflow is included at the end of this article. Its useful path has three steps:

1. A chat is resolved. The native Wassenger trigger listens for a real chat:update event whose action is resolve.
2. The AI agent audits the evidence. It consults the configured criteria and the recent text messages through bounded tools.
3. Wassenger marks the conversation for a person. A native Wassenger node creates a private note and another adds the review label.

The default criteria cover three observable problems:

The distinction between observable and assumed problems matters. A call, payment, appointment or task outside WhatsApp may have happened even if the chat does not show it. The agent is instructed not to treat that absence as proof. It can return insufficient evidence instead of inventing a failure.

Why this is an agent, not a fixed keyword rule

A keyword rule can find the word “quote.” It cannot reliably decide whether the quote was already sent, whether the customer was asking a question or whether a later message resolved the issue.

This Flow gives the agent three read-only tools:

The agent chooses which evidence it needs, but its output is not trusted automatically. A validation node rejects criteria, policies or message IDs that were not actually returned by those tools. This lets the reasoning stay flexible while keeping the final finding tied to records from that execution.

You can adapt the Flow without rewriting its JavaScript. Edit Tu criterio to change the business name, language, label, severity threshold, criteria and policies. Keep each ID short and stable so the evidence remains easy to trace.

What appears in the inbox

For the tested quote scenario, the agent returned:

• verdict: revisar;
• finding type: unfulfilled_chat_promise;
• severity: medium;
• the criterion ID and the two message IDs that supported the finding.

The Flow then added a private note similar to this:

Review closure: Promise to send something in this chat is pending.
Criteria: unfulfilled_chat_promise.
Policies: none.
Evidence messages: [message IDs].
Next step: a person must open these messages and decide the follow-up. Nothing was sent to the customer.

The note contains a unique marker for that closure. A sequential retry looks for the marker before creating another note. The Flow also creates the configured label when it does not exist and adds it without replacing the chat’s other labels.

The customer sees none of this. The workflow contains no node that sends a WhatsApp message. Its actions are limited to the internal note and label.

Safeguards before it changes a chat

The Flow checks more than the model’s answer. It stops before writing when the event, configuration or evidence does not meet the expected contract.

It only accepts a resolved individual chat from the WhatsApp number selected in the trigger. It reads up to 50 recent history entries and provides the agent with up to 40 valid text messages. Private notes stay outside the model’s message evidence, and non-text items are flagged as omitted.

After the agent returns a verdict, the Flow reloads the chat and its history. It does not write if the closure changed or if the observed message set is different. Test-mode executions and the example configuration also block internal writes.

These checks reduce stale or unsupported findings. They do not turn the template into an unattended production policy. The notes API has no verified idempotency key in this implementation, so two truly simultaneous deliveries for the same closure could still create duplicate notes. Test that edge case in your account and keep a person responsible for the review queue before using the Flow on customer conversations.

Configure the workflow

You need a Wassenger account with Flows, a connected WhatsApp number and an OpenAI API credential for the included model node. A ChatGPT subscription alone does not provide an API key.

1. Copy the complete workflow JSON below and save it as a workflow.json file, or keep it on your clipboard.
2. In Wassenger, open Flows and create an empty Flow.
3. Import the file, or paste the JSON into the empty canvas. Importing into an existing workflow can produce a duplicate-trigger error.
4. Open Entrada Wassenger and select the Wassenger connection and exact WhatsApp number you want to test.
5. Select the same connection and number in every native Wassenger read and action node.
6. Open OpenAI Chat Model and select your OpenAI API credential.
7. Edit Tu criterio. Replace the example business name, review the criteria and policies, choose the minimum severity, and change example to false only when the configuration is complete.
8. Save the Flow. The JSON arrives inactive so you can inspect every node first.

If you do not have written business policies to check, leave policies as an empty array. Do not add vague rules that the conversation cannot prove. A narrower list produces a more useful review queue.

Run a controlled first test

Use a WhatsApp number and a contact you control. Choose a number that is not handling customer conversations during this test: while the Flow is active, it can audit other chats resolved on that number too.

After completing the setup above, use Publish in the Flow editor to turn on the automation for your selected number. This lets a real chat closure start the Flow and create its private note and label. The editor's Test button does not create those changes with this template.

1. From the controlled contact, send: “I need a quote. Can you send it in this chat?”
2. From the team inbox, reply: “Yes, I’ll send it here now.”
3. Do not send the quote, then resolve the chat.
4. View the resolved conversation in your team inbox, keeping its status as resolved. Look for a private note explaining the missing promise and the Revisar cierre IA label, or the label you chose in Tu criterio.
5. Check WhatsApp on the contact's phone. There should be no new message from the Flow.
6. Return to the Flow editor and unpublish the Flow to turn off the automation while you review the result.

For each further test, activate the Flow only for the controlled test window and turn it off afterwards. Try the opposite case: send the promised information before resolving a fresh test conversation. That closure should finish without creating a review note. Also test a reopened chat, a group and a label-only update. None should produce a finding from this trigger.

Optional technical check

If the note or label is missing, open Executions in the Flow editor and select the run from your test. A failed node shows where processing stopped. To inspect the agent's evidence gathering, check its tool calls for consultar_criterios and consultar_mensajes. These are diagnostic details; the visible result you are testing is the private note and label, with no message sent to the contact.

What we validated

The exact JSON below imported into Wassenger Flows as an inactive workflow. Its local suite passed 13 tests covering its structure, event filtering, bounded context, tool-backed evidence, verdict validation and sequential retry behavior.

We then ran a controlled end-to-end test on 22 September 2026. A real resolved-chat event started the hosted workflow. The agent called the criteria and message tools, classified the missing quote as unfulfilled_chat_promise, and cited the real message IDs from the conversation. The Flow reloaded the chat, created the private note, ensured the label existed and confirmed both effects in the final node. The run completed successfully in 22.511 seconds.

We inspected the conversation afterwards. The note and label were present, and no customer-facing WhatsApp message had been added. The workflow was unpublished after the test.

This evidence supports a controlled evaluation of the template. Before a wider rollout, complete your own acceptance set for no-finding conversations, unsupported content, configuration errors and simultaneous retries. Review OpenAI usage and data handling for your business before allowing customer conversation text to reach the selected model.

Complete workflow JSON

Copy the entire block into an empty Flow, or save it as a .json file and use Import from file. After import, select your own credentials and number. The template contains no credentials.
