Reonic

Reonic is a German climate-tech company (founded 2021, Augsburg) building an AI-powered operating system for renewable-energy installers. Its platform covers the full workflow for selling and installing photovoltaic systems, heat pumps, EV chargers, and battery storage — CRM and lead management, 3D roof planning and shading simulation, instant pricing, proposal generation with digital signature, project and installation tracking, and documentation. The Reonic REST API v3 exposes 111 endpoints across 33 resource areas (contacts, residential and commercial projects, tasks, files, components, planning templates, time tracking, wiki, photogrammetry, and more), authenticated with rnc_v3_ API keys, plus a 17-event signed webhook surface.

Reonic publishes 30 APIs on the APIs.io network, including Activities API, Appointments API, Calendar Categories API, and 27 more. Tagged areas include Company, Climate Energy, Solar, Renewable Energy, and Photovoltaic.

The Reonic catalog on APIs.io includes 2 event-driven AsyncAPI specifications.

Reonic’s developer surface includes documentation, API reference, engineering blog, support, signup flow, authentication, changelog, and 21 more developer resources.

Kin Score Kin Score How this is scored →
scored 2026-09-08 · rubric v0.20.0
Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/reonic: open an issue to ask a question, or submit a pull request to add artifacts.

    \ `Content-Type: application/json`), must not redirect, and must respond within 5 seconds. Acknowledge first and process\
    \ asynchronously if you need more time.\n\n<a id=\"webhooks-test-events\"></a>\n\n### Test events\n\nThe Portal test action\
    \ sends `X-Reonic-Event: test` with a `{ \"message\": … }` payload in the standard body shape (see [**Request format**](#webhooks-request-format)\
    \ below). Use it to verify reachability and signature handling before enabling production events. Test deliveries are\
    \ not retried and do not appear in the delivery log. Your endpoint's response is shown directly in the Portal instead.\n\
    \n<a id=\"webhooks-request-format\"></a>\n\n### Request format\n\nEach delivery sends a JSON body with this shape:\n\n\
    ```json\n{\n  \"version\": 1,\n  \"type\": \"project_created\",\n  \"occurredAt\": \"2026-01-01T12:00:00.000Z\",\n  \"\
    data\": { /* event-specific payload, see the events below */ }\n}\n```\n\nPayloads are deliberately thin: they identify\
    \ what happened and which resources were involved, but do not embed resource snapshots. Fetch the current state of an\
    \ affected resource through the corresponding API v3 endpoint — for example, a `project_created` delivery carries a `projectId`\
    \ to fetch via [**Residential Projects**](#tag/residential-projects) or [**Commercial Projects**](#tag/commercial-projects),\
    \ depending on its `projectType`.\n\nEvent metadata is also sent in headers:\n\n| Header | Meaning |\n|---|---|\n| `X-Reonic-Event`\
    \ | Event type for this webhook delivery. Matches the `type` field in the body. |\n| `X-Reonic-Client-Id` | Id of the\
    \ sending client. Stable across deliveries. If one endpoint receives webhooks from multiple clients, use this to pick\
    \ the matching signing secret before verifying the signature. |\n| `X-Reonic-Event-Id` | Stable event id, identical across\
    \ redeliveries of the same event. Use this as your idempotency key. |\n| `X-Reonic-Delivery-Id` | Unique id of this delivery\
    \ attempt. Unlike the event id, it changes on every redelivery — reference it when reporting issues with a specific delivery.\
    \ |\n| `X-Reonic-Timestamp` | Unix timestamp in seconds at which this delivery was signed. Changes on every redelivery\
    \ — verify signatures against this value, not the body's `occurredAt`. |\n| `X-Reonic-Signature` | HMAC SHA-256 signature\
    \ in the format `sha256=<hex>`, computed over `${timestamp}.${rawBody}`. |\n\n<a id=\"webhooks-verify-signatures\"></a>\n\
    \n### Verify signatures\n\nVerifying signatures is optional but strongly recommended: it proves a delivery was really\
    \ sent by Reonic and not by someone who discovered your URL. If your tool cannot compute HMAC digests, keep your webhook\
    \ URL secret and treat the data accordingly.\n\nCompute an HMAC SHA-256 digest with your webhook signing secret over `${timestamp}.${rawBody}`,\
    \ then compare it to `X-Reonic-Signature`. Use the raw request body exactly as received, before JSON parsing. Reject deliveries\
    \ whose `X-Reonic-Timestamp` is more than 5 minutes old to reduce replay risk — retries are signed freshly, so a legitimate\
    \ delivery never carries an old timestamp.\n\nCode example:\n\n```ts\nimport { createHmac, timingSafeEqual } from \"crypto\"\
    ;\n\nconst timestamp = request.headers[\"x-reonic-timestamp\"];\nconst signature = request.headers[\"x-reonic-signature\"\
    ];\n\nconst expected = Buffer.from(\"sha256=\" + createHmac(\"sha256\", secret)\n  .update(`${timestamp}.${rawBody}`)\n\
    \  .digest(\"hex\"));\nconst received = Buffer.from(signature);\n\nconst isValid = expected.length === received.length\
    \ && timingSafeEqual(expected, received);\n```\n\n### Retries and idempotency\n\nRespond with any `2xx` status code once\
    \ you have accepted the event — automation tools like Zapier and n8n do this for you. Every other response, as well as\
    \ network errors and timeouts, is retried automatically, roughly 1 min, 5 min, 30 min, 2 h, 5 h, 12 h, 1 d, 2 d after\
    \ the initial attempt.\n\nDelivery order is not guaranteed, and the same event may be delivered more than once, so store\
    \ `X-Reonic-Event-Id` and ignore duplicates.\n\n> [!warning]\n> If all retries are exhausted, Reonic disables the webhook\
    \ subscription and notifies your workspace's contact email. Re-enable it in the webhook settings once your endpoint is\
    \ fixed.\n\n### When deliveries fail\n\nThe webhook settings in the Portal include a delivery log with every attempt,\
    \ the response status or error we recorded, and the payload that was sent. Failed deliveries can be retried manually from\
    \ there — including after you fix your endpoint and re-enable a disabled subscription.\n\n### Compatibility\n\nThe body's\
    \ `version` (currently 1) only changes when the envelope shape itself — `version`, `type`, `occurredAt`, `data` — changes\
    \ in a breaking way. New event types, new fields inside `data`, and new headers may appear without a version bump, so\
    \ ignore anything you don't recognize."
