Funcionalidades do WhatsApp Business API para Cobrança

Recursos projetados para transformar o atendimento no segmento de cobrança.

Official API allows high message volume within Meta's policies without the risk of blocking.

Webhooks and native integrations

Connect existing systems like ERP, CRM, and e-commerce via documented RESTful API.

Multi-number and multi-agent

Official WhatsApp API

Direct connection to Meta's official API, ensuring stability, speed, and compliance with policies.

Green verification badge

Assisted process for obtaining the verified badge that increases trust and message open rates.

Account verification and official seal

Nexloo handles the business verification with Meta and the request for the badge. The client sees the company's name instead of a random number — and decides in seconds whether to respond.

No limit on connected devices

How many agents do you need at the same number, without a phone on the desk and without the instability of keeping a device connected all day long.

Approval of models accompanied

You write the model, the platform sends it to Meta, and shows the status. Rejections come with a reason, and adjustments are made before the campaign relies on them.

24-hour window controlled

Within the window, the conversation is free and without model costs; outside of it, only approved templates are sent. The platform shows the status of each conversation.

Delivery and read receipt

Sent, delivered, and read come as the status of each message. For billing and mandatory communication, this record is the difference between notifying and proving that you notified.

Click-to-WhatsApp ads

Meta campaigns that open a conversation go directly to the official number, with the source campaign tagged in the contact — and attribution stops being a guess.

Quality monitor of the number

Meta maintains a quality indicator on your number and limits sending when it drops. The platform monitors this indicator and alerts before the limitation.

Sending tier escalation

The daily conversation limit increases according to the number's history. The platform shows what step you are on and what is needed for the next one.

Migration of the number you already use

The current number can be migrated to the API while keeping customer contacts. There's no need to share a new number or restart the database.

What's changing

Reported. Now prove it.

Billing is the area where the record is as valuable as the message. Without proof of delivery, the first dispute turns a correct notice into an unproven claim.

The operation, compared

Scenario
  • Billings with proof of delivery — today15%
  • Billings with proof of delivery — with the API100%+85 p.p.
  • Disputes without proof of notice — today38%
  • Disputes without proof of notice — with the API3%−35 p.p.

Illustrative scenario, not customer measurements. The percentages are meant to compare the two modes of operation and vary according to each company's process. The example considers a collection operation with the obligation to prove communication.

In practice

How the scale turns verified communication

The charge via API has four requirements, and all four protect both the one charging and the one being charged.

  1. The model is approved and categorized

    Due date notice is utility-based; the correct category avoids rejection and reduces costs.

  2. The sending keeps the receipt

    Sent, delivered, and read are recorded per message, with timestamps.

  3. Opt-out is respected

    Those who request to opt-out no longer receive any campaigns — and the request is recorded.

  4. The response turns into negotiation

    Those who respond open the 24-hour window, and the table negotiates without additional model costs.

Does the WhatsApp Business API for Collections integrate with other company tools?

How long does it take to set up the WhatsApp Business API for Collections?
