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

Webhooks and native integrations

Official WhatsApp API

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

The customer talks to you or with the office?

Using personal cell phones ties the client to the lawyer and not the firm. When they leave, they take the relationship and history with them — and the firm realizes the extent of this later.

The operation, compared

Scenario
  • Communications through the office number — today16%
  • Communications through the office number — with the API100%+84 p.p.
  • History that goes out with the lawyer — today49%
  • History that goes out with the lawyer — with the API2%−47 p.p.

Illustrative scenario, not client measurements. The percentages are meant to compare the two modes of operation and vary according to each company's process. The example considers an office where communication happens via personal cell phones.

In practice

How does the team take over the channel with the customer

Institutional number, access by area, and a notice that does not reveal content — the three conditions for communicating without breaking confidentiality.

  1. The office is verified

    The panel appears by name, and the client recognizes the sender before opening.

  2. The reminder reveals nothing

    The template indicates that there has been movement and invites — the content stays in the conversation.

  3. Access follows the area

    Each conversation is visible to those handling the case, with revocation when someone leaves.

  4. The history remains.

    The departure of a lawyer does not affect the relationship or the record of what was advised.
