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 WhatsTeam Flow looks for. A Flow is an automation you build in WhatsTeam's visual editor, step by step. This one starts when someone on your team resolves a one-to-one WhatsApp chat. An AI agent reads the recent conversation, checks your review rules and decides whether the closure needs a person to look at it. If the evidence is clear, the Flow adds a private note and the label Revisar cierre IA (Spanish for “review AI closure”; you can rename it). It sends nothing to the customer.

In a test of the original template on the same platform, the Flow found the unkept promise, quoted the two messages that proved it, created the private note and added the review label. It sent nothing to the customer: its last step reported customerMessagesSent: 0.

This gives a business owner or support manager a practical review queue. A person still decides what to do next, but nobody has to reopen every resolved conversation to find the few that deserve attention.

What the Flow does

The complete template is at the end of this article. Its useful path has three steps:

1. A chat is resolved. The Flow starts when someone marks a chat as resolved.
2. The AI agent checks the evidence. It reads your review rules and the recent text messages through a few limited tools.
3. WhatsTeam flags the conversation for a person. One WhatsTeam node creates a private note and another adds the review label.

The example rules cover three problems you can see in the chat itself:

The difference between what you can see and what you assume matters. A call, payment, appointment or task outside WhatsApp may have happened even if the chat doesn't show it. The agent is told not to treat that gap as proof. It can answer insufficient evidence instead of inventing a failure.

Why this is an agent, not a keyword rule

A keyword rule can find the word “quote.” It can't reliably tell whether the quote was already sent, whether the customer was asking a question or whether a later message settled the matter.

This Flow gives the agent three read-only tools. Their names are in Spanish inside the template:

The agent chooses which evidence it needs, but its answer isn't trusted automatically. A checking step rejects any rule, policy or message ID that those tools didn't actually return. The reasoning stays flexible, while every finding stays tied to real records from that run.

You can adapt the Flow without touching its code. Edit the node Tu criterio (“your criteria”) to change the business name, the label, the minimum severity, the rules and the policies. Keep each ID short and stable, so the evidence stays easy to trace.

One thing you can't change there is the language of the note. The note is always written in Spanish. Tu criterio has a language setting, but it is only passed to the AI agent. It doesn't change the note, whose wording is fixed inside the template.

What appears in the inbox

In a test of the original template on the same platform, the agent returned:

• verdict: revisar (review);
• finding type: unfulfilled_chat_promise;
• severity: medium;
• the rule ID and the two message IDs that supported the finding.

The Flow then added a private note like the one below. The note comes out in Spanish, whatever language your team uses, so the English meaning of each line is in brackets:

QA:CLOSE:v1:number, chat and closing time [a marker that identifies this closure]
Revisar cierre: Compromiso de envío por este chat pendiente. [Review closure: a promise to send something in this chat is pending.]
Criterios: unfulfilled_chat_promise. [Criteria: unfulfilled_chat_promise.]
Políticas: ninguna. [Policies: none.]
Mensajes de evidencia: message IDs. [Evidence messages: the message IDs.]
Siguiente paso: una persona debe abrir estos mensajes y decidir el seguimiento. No se ha enviado nada al cliente. [Next step: a person must open these messages and decide the follow-up. Nothing has been sent to the customer.]

The first line is a unique marker for that closure. If the Flow runs again for the same closure, it looks for the marker before creating another note. The Flow also creates the label if it doesn't exist yet, and adds it without removing the chat's other labels.

The customer sees none of this. The template has no step that sends a WhatsApp message. All it can do is add the internal note and the label.

Safeguards before it changes a chat

The Flow checks more than the AI's answer. It stops before writing anything when the event, the setup or the evidence isn't what it expects.

It only accepts a resolved one-to-one chat from the WhatsApp number selected in the trigger. It reads up to the last 50 items in the chat and gives the agent up to 40 text messages from them. Private notes are kept out of the agent's message evidence, and anything that isn't text is marked as left out.

After the agent answers, the Flow reads the chat and its messages again. It doesn't write if the closure changed or if the messages are different from the ones it checked. Runs started with the editor's Test button never write anything, and neither does the example setup.

These checks reduce out-of-date or unsupported findings. They don't make the template something you can leave running unwatched. If the same closure reaches the Flow twice at exactly the same moment, the template can't yet tell the two apart, so that chat could end up with two notes. Test that case on your account, and keep a person responsible for the review queue before you use the Flow on customer conversations.

Configure the workflow

You need a WhatsTeam account on the Business or Enterprise plan, which include Flows (see plans and prices), a connected WhatsApp number and an OpenAI API credential for the included AI model node. A ChatGPT subscription on its own doesn't give you an API key.

1. Copy the complete JSON below (the text that describes the Flow) and save it as a workflow.json file, or keep it on your clipboard.
2. In WhatsTeam, open Flows and create an empty Flow.
3. Import the file, or paste the JSON into the empty canvas. Use an empty Flow, because importing into one that already has steps can make the import fail.
4. Open Entrada WhatsTeam (the trigger) and select the WhatsTeam connection and the exact WhatsApp number you want to test.
5. Select the same connection and number in every WhatsTeam node that reads or changes the chat.
6. Open OpenAI Chat Model and select your OpenAI API credential.
7. Edit Tu criterio. Replace the example business name, review the rules and policies, choose the minimum severity, and change example to false only when the setup is complete.
8. Save the Flow. The JSON arrives switched off, so you can look at every step first.

If you don't have written business policies to check, leave policies as an empty list. Don't add vague rules that a conversation can't prove. A shorter list gives you a more useful review queue.

Run a controlled first test

Use a WhatsApp number and a contact you control. Pick a number that isn't handling customer conversations during the test: while the Flow is on, it can review any other chat resolved on that number too. That includes chats closed by auto-resolve, because those count as a normal closure too.

After the setup above, click Publish in the Flow editor to switch the automation on for your number. A real chat closure can now start the Flow and create the note and label. The editor's Test button doesn't make those changes with this template.

1. From the test 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. Don't send the quote. Resolve the chat.
4. Open the resolved conversation in your team inbox and leave it 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. Go back to the Flow editor and unpublish the Flow to switch the automation off while you review the result.

For each further test, switch the Flow on only for that test and off again afterwards. Try the opposite case: send the promised information before resolving a fresh test conversation. That closure should finish without a review note. Also test a reopened chat and a change that only adds a label. Neither should produce a finding.

If something is missing

If the note or label doesn't appear, open Executions in the Flow editor and select the run from your test. A failed step shows where it stopped. To see how the agent gathered evidence, check its calls to consultar_criterios and consultar_mensajes. These are only for diagnosis: the result you're testing is the private note and label, with no message sent to the contact.

What we validated

Before we prepared this WhatsTeam version, the template passed its own 13 automatic tests. They covered how it is built, which closures start it, how much of the chat the AI sees, whether its findings match real messages, how the AI's answer is checked and what happens when it runs twice for the same closure.

In a test of the original template on the same platform, run from start to finish on 22 September 2026, closing a real chat started the Flow. The agent called the rules and messages tools, classified the missing quote as unfulfilled_chat_promise and quoted the real message IDs from the conversation. The Flow read the chat again, created the private note, made sure the label existed and confirmed both changes in its last step. The run finished in about 23 seconds.

The conversation was checked afterwards. The note and label were there, and no message had gone to the customer. The Flow was unpublished after the test.

The version below uses the WhatsTeam nodes. We checked that it is valid JSON, that every WhatsTeam node and action in it exists, that it carries no credentials and that every step it refers to is in the file. We haven't run this exact version on a WhatsTeam number yet, so treat your own controlled test as the first one.

This supports a controlled trial of the template. Before using it more widely, run your own set of checks: conversations with nothing to flag, content it doesn't support, setup mistakes and the same closure arriving twice at once. Review OpenAI's charges and data handling for your business before letting customer conversations reach the AI model.
