There are several APIs designed for the modules in the WatchWire platform including - Invoice Data, Real-Time, Accounts Payable, and Measurement & Verification. All are highly scalable, and secure APIs that communicate over HTTPS RESTful protocols with JSON based documents. > **Note**: Not all WatchWire modules are available as an API. # Authentication You need credentials to access the APIs - it is the same credentials as your WatchWire login. The `/authenticate` will return a Token that needs to be included in the header of every subsequent request. The token renews with each request and expires after 60 minutes of inactivity (at which point you will need to re-authenticate and get a new token). > Please contact the WatchWire team for any questions or request for API credential access. # Error Codes There will be various error codes specific to the API you are using, but generally follows these principles: * `Unauthorized` - *you are unauthenticated or unauthorized to request actions on an asset* * `Asset doesn't exist` - *the item you are querying for doesn't exist* * `Server error`\- *general exception raised in our application code* # Rate limit Rate limited to 10 transactions per meter / second servers: - url: https://auth.replace-me.example.com description: Authentication service (Postman variable {{ww-api-baseurl}}) - url: https://realtime.replace-me.example.com description: RealTime API (Postman variable {{gateway-realtime-api}}) - url: https://ap.replace-me.example.com description: Accounts Payable API (Postman variable {{gateway-ap-api}}) - url: https://invoice.replace-me.example.com description: Invoice API (Postman variable {{portal-api-baseurl}}) - url: https://mv.replace-me.example.com description: Measurement & Verification API (Postman variable {{invoice-api}}) security: - BearerAuth: [] tags: - name: Authentication - name: RealTime API - Custom Meter - name: RealTime API - Meter Readings - name: RealTime API - Meter Readings Aggregations - name: RealTime API - Meter Readings Batch Operations - name: RealTime API - Obvius Meter Readings - name: Accounts Payable API - Audit Statements - name: Accounts Payable API - Nexus Statements - name: Accounts Payable API - Standard Statements - name: Accounts Payable API - Statement PDFs - name: Invoice API - Reference IDs - name: Invoice API - Invoice - name: Measurement & Verification API - M&V paths: /mv/projects/{projectIds}: post: tags: - Measurement & Verification API - M&V summary: Get measurement and verification project details description: >- Request measurement and verification project details for a list of projectIds operationId: getMeasurementAndVerificationProjectDetails parameters: - name: projectIds in: path required: true schema: type: string description: Comma separated Project IDs of measurement and verification projects responses: '200': description: Successful response content: application/json: schema: type: object properties: projects: type: array items: type: object properties: projectId: type: integer energyUnit: type: string name: type: string energyRate: type: number energyCommitment: type: number remainingCommitment: type: number totalUsageSavings: type: number totalCostAvoidance: type: number totalCarbonImpact: type: number totalRetainedSavings: type: number monthlyBreakdown: type: array items: type: object properties: monthYear: type: string monthlyProjectedUsage: type: number monthlyBaseline: type: number monthlyWeatherAdj: type: number useSavings: type: number costSavings: type: number costPerKwh: type: number projectedCost: type: number historicalBaseline: type: number historicalWeatherAdj: type: number carbonImpact: type: number actualUsage: type: number actualCost: type: number savedEnergyPayment: type: number retainedSavings: type: number month: type: integer year: type: integer example: projects: - projectId: 74368858 energyUnit: fugiat sunt aliquip name: quis et cillum laborum energyRate: -10376013.663538113 energyCommitment: 46421382.33169901 remainingCommitment: 57966680.93217087 totalUsageSavings: -87605593.80103698 totalCostAvoidance: 63427154.611405015 totalCarbonImpact: 76694930.27435297 totalRetainedSavings: 16681948.501847848 monthlyBreakdown: - monthYear: Jan 2016 monthlyProjectedUsage: -39728550.587629564 monthlyBaseline: 16282316.62023434 monthlyWeatherAdj: -22461828.00309664 useSavings: 62942300.17243886 costSavings: -81156836.01591104 costPerKwh: 96065775.08208582 projectedCost: 32191853.3848387 historicalBaseline: -87727260.33971949 historicalWeatherAdj: 55965201.22681245 carbonImpact: -73111776.74431999 actualUsage: -27365353.86962165 actualCost: 35043112.33222467 savedEnergyPayment: -46629989.27023927 retainedSavings: -72818250.28728974 month: -87008828 year: -29197503 '400': description: Invalid ID supplied '401': description: Unauthorized - missing, invalid or expired token '403': description: Unauthorized access to id security: - TokenHeader: [] servers: - url: https://mv.replace-me.example.com description: Measurement & Verification API (Postman variable {{invoice-api}}) components: securitySchemes: BearerAuth: type: http scheme: bearer description: >- Token returned by `POST /authenticate`.
