Quick answer
An API defines how software can interact; a webhook sends a notification to a configured endpoint when an event occurs. Integration behavior, permissions and delivery guarantees depend on each provider’s documentation.
Answer: An API is an interface through which software can interact with another system. A webhook is an event notification sent to a configured receiving endpoint, often over HTTP. Solar teams can use supported interfaces to connect CRM, design, proposals or operations, but an API does not guarantee every action is available, and a webhook does not guarantee immediate or exactly-once workflow completion.
API requests and webhook notifications
In a common HTTP API workflow, an application requests a record or submits a supported change and receives a response. A webhook instead notifies a receiver that a subscribed event occurred. APIs are broader than HTTP request-response alone; REST is one interface style, not a universal requirement for solar software.
A notification may contain the full relevant data or only identifiers that let the receiver retrieve a record. Check the schema, permissions and version. “Design complete” can also have different meanings across platforms: it may describe a user status rather than engineering approval.
Possible solar workflow connections
These are integration patterns to evaluate, not statements that SurgePV or every other provider supports them:
| Connection | Possible data | Review needed |
|---|---|---|
| CRM to design | Project identifier, address and consumption inputs | Field mapping, units, customer permissions and duplicate handling |
| Design to proposal | Design revision, equipment and production basis | Proposal linked to the correct reviewed revision |
| Signed proposal to operations | Contract identifier and status | Valid signature state, scope, cancellations and approval gates |
| Installation to monitoring | Equipment identifiers and commissioning records | Device mapping, accepted baseline and access rights |
A financing request is not loan approval. A generated permit package is not permit acceptance. An integration with an ordering endpoint does not mean that a proposed BOM has been reviewed or that an order should be placed automatically.
What to check before choosing an integration
Ask for the provider’s current documentation and account-specific access conditions:
- Supported endpoints and event types, required plan or permissions, authentication and tenant separation.
- Field definitions, units, time zones, project IDs and design revision IDs.
- Read versus write access, pagination, rate limits, error responses and version changes.
- Webhook validation method, payload schema, delivery identifier, retry behavior and retention.
- Sandbox access, audit logs, incident ownership and a supported recovery process.
Native connections and no-code platforms can simplify implementation, but still need configuration, field mapping, access control and failure handling. Verify each required trigger and action instead of assuming two advertised integrations form a complete pipeline.
Design for repeated, delayed or missing deliveries
As a specific implementation example, GitHub’s webhook guidance covers HTTPS, webhook secrets, event filtering, missed deliveries and delivery identifiers. Its timing and headers are provider-specific; do not apply its exact rules to another vendor. GitHub webhook best practices.
Hypothetical solar handoff: a design system sends event evt-104 for project P-27, revision R-3. The receiver authenticates the delivery using the documented method, checks that the event is supported, records its identity and queues the work. If the same delivery is retried, the receiver should avoid creating a second proposal for that event.
Before publishing the proposal, it also checks whether R-3 is still the approved revision. A later R-4 event can arrive before an earlier notification; arrival order alone must not overwrite the current project state. Where supported, retrieve the current authoritative record and reconcile missed events on a defined schedule.
This is a design example, not a tested SurgePV endpoint, event schema or retry guarantee. Use actual provider identifiers and documented semantics. Keep personal data and credentials out of logs and URLs, limit shared data to the workflow need, and control access to stored records.
Measure operational value honestly
Estimate avoided work and then account for exceptions, maintenance and integration costs. Hypothetical capacity example: 100 projects per month × 3 avoided steps × 5 minutes per step equals 1,500 minutes, or 25 hours per month. At an assumed $30/hour, that is $750/month of gross labor capacity, before setup, subscription, support and exception-handling costs. It is not a guaranteed cash saving or ROI.
Designers should define which design version and evidence move downstream. Operations should own exception queues and reconciliation. Sales teams should verify consent and approvals before a signed-contract event triggers sensitive submissions or purchases.
See CRM integration, proposal API and incentive API for related concepts. To evaluate a required workflow, book a SurgePV demo and request documentation for the specific integration and account being considered.
Frequently asked questions
Is a webhook an instant, guaranteed update?
No. Delivery and processing can be delayed or fail. Read the provider’s guarantees and build the required recovery behavior.
Do I need a developer?
It depends on supported native connections, workflow complexity and reliability requirements. No-code configuration still requires testing and an accountable owner.
Does API access mean every workflow can be automated?
No. The necessary endpoints, events, permissions and partner capabilities must exist. Preserve required customer, technical and commercial approvals.
Can a successful HTTP response prove the downstream task finished?
Not necessarily. It may acknowledge receipt or queueing. Check the documented completion status and audit the actual task outcome.
