Integrating a charging API into your app, CRM and portal
A charging API can bring EV charging into your existing app, CRM or customer portal. A clear customer journey, suitable data flows and defined responsibilities are essential. StromNow offers API integration as part of its white-label solution. The functions and data included in your project are agreed together.
What does a charging API mean for your business?
An API connects software systems. For your charging service, this means your existing digital touchpoints can work with the charging platform. You can plan the customer journey around the places your customers already use. Decide where charging makes sense for them first, then discuss the technical implementation.
StromNow lists customers and charging cards, charging points, tariffs and charging sessions, as well as vehicle and home charger integration among its API areas. These provide a starting point for a project discussion. The functions, access and data available for your particular use case still need to be confirmed.
Three useful touchpoints: app, CRM and portal
Your existing app as the starting point
If customers already open your app regularly, it can also be a useful entry point to your charging service. Consider what they actually need to do: understand the offer, begin registration, associate a charging card or find information about a session. A small, clear first use case is easier to test than a screen filled with new functions.
Your CRM for customer context
The CRM supports your relationship with the customer. Plan which information your service team needs to answer questions and which system remains the source of truth. Uncoordinated copies of the same data make support harder. The integration should therefore have clear account mappings and rules for updates.
Your customer portal for ongoing clarity
A portal can provide a place to show a charging service alongside existing contracts or services. Decide which information customers should be able to view or change themselves. A clear presentation is especially useful when charging cards, tariffs and several digital entry points belong to the same offer.
Plan data flows and responsibilities first
Map a specific journey from initial interest to a service request. For each step, record which system provides data, who can initiate changes and which team handles problems. Start with a few realistic examples, such as a new customer registering or someone losing a charging card.
Also decide how an existing customer account should connect to the charging service. Sign-in, permissions, consent, data retention and internal approvals belong in your technical and operational planning. Clarify authentication methods, interfaces and permission models during the integration discussion and document the agreed requirements.
Show charging information in the right context
A charging point, a displayed tariff and a completed session serve different purposes. Search helps customers decide where to charge. Session history helps answer questions later. For each view, describe the information required and agree how its freshness should be handled within your integration scope.
Vehicle and home charger compatibility also needs to be checked. Available vehicle data and controls depend on the model and manufacturer account. Plan a clear customer flow for unsupported connections or those that still need to be set up. This keeps the interface understandable when a customer cannot complete the ideal journey.
Checklist for your integration discussion
Describe your audience, main use case and preferred entry point.
List your existing app, CRM, portal and the internal teams involved.
Define the source of truth for customer accounts and core data.
Prioritise the data and actions needed in the first project phase.
Clarify permissions, privacy review and responsibility for changes.
Discuss how tariff information, transactions and billing questions fit together.
Plan service cases such as a lost card, missing account mapping or incomplete data.
Agree the pilot scope, test cases and clear approval criteria.
Test the whole customer journey in a pilot
Successful data exchange alone does not establish a good customer experience. Ask pilot customers whether they understand the entry point, can find the information they need and know where to get help. Check that your service team can understand a case without a lengthy investigation.
Record unresolved points with an owner and a next step. Expand the scope once the agreed flows have been checked. This makes decisions traceable and gives your team a sound basis for ongoing operations.
