Which OCPP URL do I enter on a Zaptec for askacharge.com?

wss://askacharge.com/askacharge/ocpp/your-brand, where your-brand is the brand identifier on askacharge.com; the charger appends its identity. The identity must match the one registered in the panel and the password stays blank unless the charger's OCPP credential has been enabled.

Do I lose the manufacturer's app when I set OCPP on a Zaptec?

Some app functions move to the OCPP platform (start, cards, statistics). The hardware stays the same and you can go back by changing the URL again.

How to change the OCPP server URL on a Zaptec charger (Go) and connect it to another platform

Q: Can a Zaptec charger be connected to a platform other than the manufacturer's?

Yes. The Go, Go 2, Pro models speak standard OCPP and let you change the server URL. In the Zaptec Portal (portal.zaptec.com): Installations → your installation → Settings → Authentication → Type. It is a setting for the whole installation, not per charger.

A Zaptec charger that speaks standard OCPP can be connected to any platform by changing one setting. Here is where that setting lives on Go, Go 2, Pro, exactly what to enter, and where people usually get stuck. Written by a platform (askacharge.com), but the procedure works for any.

Where the setting lives

In the Zaptec Portal (portal.zaptec.com): Installations → your installation → Settings → Authentication → Type. It is a setting for the whole installation, not per charger.

Step by step

Update the firmware from the portal. Minimums for native OCPP: Go EU 2.4.2.4, Go UK 2.5.1.0, Go 2 3.2.1.0, Pro 7.5.4.0.
Permissions: under User Groups in the portal, Allow OCPP 1.6J must be enabled for your organisation. If another company administers the installation, the owner has to grant you access (four-character partner key).
Make sure every charger is online and no charging session is running; otherwise the mode change is not applied.
Installations → your installation → Settings → Authentication → Type: switch to OCPP 1.6J authentication.
In OCPP Central System URL enter your brand's base URL (below), without the serial number: Zaptec appends it by itself, in upper case. Leave Initial device password blank unless you use the panel credential.
Save. Each charger's identity is its serial number (ZCS…, ZAP…) in upper case: register it like that in the panel. They show as connected within a couple of minutes.

What to enter to connect it to askacharge.com

OCPP server URL	`wss://askacharge.com/askacharge/ocpp/your-brand` — your-brand is your brand's identifier on askacharge.com (shown under Chargers → Add, with the full URL ready to copy). The charger appends its own identity; if your unit only has a URL field and no identity field, enter the full URL: `…/ocpp/your-brand/identity`.
Charge point identity	The same one you register in the panel when adding the charger. Case-sensitive. With Zaptec, the serial number is the easiest choice.
Password	Blank by default. If you enable the charger's OCPP credential in the panel (recommended for units exposed to the internet), the username is the identity and the password is the one the panel generates: OCPP Security Profile 2.
Protocol	OCPP 1.6J (JSON) or OCPP 2.0.1. Subprotocol `ocpp1.6` / `ocpp2.0.1`.
Before connecting	The charger must be registered in the brand with that identity; otherwise the server rejects the connection. Register under Chargers → Add.

Where it usually fails

With native OCPP you lose Zaptec's own phase and load balancing; what remains is the standard OCPP smart charging the platform sends. The other mode, OCPP Cloud, keeps the balancing but goes through Zaptec's cloud and needs an agreement with them.
If Authorization required is off, the charger sends an empty idTag and sessions are attributed to nobody: turn it on or set a Default ID tag.
Do not put the serial number in the URL: it would appear twice and the server rejects the connection.

If your brand isn't here

The procedure is always the same; what changes is where the setting lives: look in the manufacturer's app, in the charger's web interface (by its IP) or in the installer software for a section called OCPP, Back office, Central System or Server. You need to be able to enter the URL and, nearly always, the identity. If the field is locked or missing, the manufacturer has tied the charger to its own platform: read what to do when the manufacturer locks or switches off its server.
