If the WhatsApp QR code does not appear when trying to add an inbox in Papo Global (https://papo.global/), the problem is usually the type of connection chosen or browser blocks. Papo offers two ways to connect a number: via Meta's official API (Cloud API), which does not use a QR code, and via providers like Evolution or WAHA, which use QR pairing. Check which method you selected and follow the corresponding instructions.
Summary of causes and solutions
| Probable cause | What to check | Recommended action |
|---|---|---|
| Incorrect connection method | You expect a QR code, but the connection is via Meta's official API | Use the "WhatsApp – API Cloud (Meta)" option only with credentials; for QR, choose a compatible provider |
| Browser block | Pop-ups, privacy extensions, or restrictive browsing mode | Disable ad blockers, allow pop-ups on the Papo site, and try Chrome in an incognito window |
| Session or cache conflict | Cookies or stored data interfering with QR loading | Clear browser cache and cookies, or test in another browser |
| Number already linked to another API or device | The same number is already being used in another WhatsApp integration (official, Business App, etc.) | Remove the previous link or release the number before trying again |
| Provider (Evolution, WAHA, etc.) unavailable | The provider's server may be down or under maintenance | Wait and try later; if the problem persists, contact the provider |
Why does the QR code disappear in some attempts?
The display of the QR code depends on the connection method you select:
- Connection via Meta's official API (Cloud API): does not display a QR code. The inbox is created by manually entering the access token, phone number ID, and business account ID, all in the Papo form.
- Connection via provider (Evolution, WAHA, Papo, etc.): uses a QR code to pair the number with the provider's API. Papo's configuration screen shows the QR only if the provider is accessible and the browser is not blocking generation.
If you chose the "WhatsApp – API Cloud (Meta)" option and expected a QR, the system will not generate the image. In that case, proceed with your Meta account credentials, as explained in the first channel guide.
Step-by-step to diagnose and resolve
1. Check which connection method you are using
- Go to Settings → Inboxes.
- Click Add inbox and observe the available options.
- If you selected WhatsApp – API Cloud (Meta): the process asks for phone number identification, business account ID, and token. There will be no QR.
- If you selected a provider (Evolution, WAHA, etc.): the next screen should show a QR code.
If you want to connect via QR, choose a provider compatible with your installation.
2. Adjust browser permissions
When the QR code should appear and does not load:
- Use Google Chrome (updated version) – it is the recommended browser for Papo.
- Disable ad blockers and extensions that block scripts (such as uBlock Origin, AdBlock, Privacy Badger).
- Allow pop-ups for the domain
papo.global. Go to the site settings in Chrome and check if "Pop-ups and redirects" is set to "Allow". - Try an incognito window (Ctrl+Shift+N) without active extensions.
After the changes, reload the inbox page and see if the QR is displayed.
3. Clear cache and switch browsers
Cache buildup can interfere with QR loading.
- In Chrome, go to Settings → Privacy and security → Clear browsing data, choose "All time" and check "Cached images and files" and "Cookies and other site data".
- Alternatively, test in another browser (Firefox, Edge) with the same permissions granted.
4. Check if the number is already linked
The same WhatsApp number cannot be connected to two APIs at the same time. If it is already:
- Registered in Meta's official API in another application,
- Logged into WhatsApp Business App on another phone,
- Or linked to another provider (Evolution, WAHA, etc.),
QR generation may be blocked. In that case, release the number: remove the previous link and only then try the new connection in Papo.
5. Confirm provider availability
If you are using a provider like Evolution or WAHA and the QR does not appear, the provider's server may be temporarily down. Papo only displays the QR when the provider responds. Contact the provider's support to check the status, then refresh the page in Papo.
Who is this guide useful for?
- Professionals who are setting up WhatsApp in Papo for the first time and expect a QR code.
- Users who want to connect a number via a provider (Evolution, WAHA, etc.) and encounter a blank screen.
- Teams that changed integration methods and do not know if the QR is necessary.
Frequently asked questions
Do I need a QR code to connect my official WhatsApp Business number?
No. The recommended connection is via Meta's official API (Cloud API), which uses credentials, not a QR code. The QR appears only when you choose a provider like Evolution or WAHA.
Why doesn't the QR appear even after I disabled the ad blocker?
Some extensions may still block specific scripts. Try an incognito window (all extensions disabled) or use Chrome without any add-ons. Clearing the cache also helps.
I chose the API Cloud (Meta) and clicked "Add inbox", but I didn't see the QR. Is that correct?
Yes. The API Cloud does not display a QR code. The form will ask you to paste the access token, the phone number ID, and the business account ID. Proceed with this data.
The QR disappeared after I reloaded the page. What to do?
The provider session may have expired. Close the inbox configuration, return to the inbox list, and try creating a new inbox with the same provider, repeating the selection step. If the problem continues, check the provider.
My number is already in WhatsApp Business on my phone. Does that prevent the QR?
Yes, if the number is logged into the WhatsApp Business app, there may be a conflict. Remove the number from the phone (delete the account or disconnect) before trying to pair via QR with the provider.
What to do if none of this solves it?
Request technical assistance directly from the Papo panel or consult the help center. Contact details are available on the platform.
