Postman Url create Record in Crm Dynamics

Question

I have to create a record in a non system entity in Dynamics (ac_sejour) with Postman. I tried many kind of requests and i have a 400 Bad Request issue. example of requests that i made:

{{ressource}}/api/data/v9.2/ac_sejours OR {{ressource}}/api/data/v9.2/entities/ac_sejours

• I put the Data Json in the body section

The error i have is the following:

"error": {
    "code": "0x0",
    "message": "Error identified in Payload provided by the user for Entity :'ac_sejours', For more information on this error please follow this help link https://go.microsoft.com/fwlink/?linkid=2195293  ---->  InnerException : Microsoft.OData.ODataException: Cannot convert the literal '11122223333' to the expected type 'Edm.String'. ---> Microsoft.OData.ODataException: Cannot convert a value of type 'Edm.Decimal' to the expected target type 'Edm.String'.\r\n   at Microsoft.OData.ODataPayloadValueConverter.ConvertFromPayloadValue(Object value, IEdmTypeReference edmTypeReference)\r\n   --- End of inner exception stack trace ---\r\n   at Microsoft.OData.ODataPayloadValueConverter.ConvertFromPayloadValue(Object value, IEdmTypeReference edmTypeReference)\r\n   at Microsoft.Crm.Extensibility.ODataV4.CrmPrimitivePayloadValueConverter.ConvertFromPayloadValue(Object value, IEdmTypeReference edmTypeReference)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightReaderUtils.ConvertValue(Object value, IEdmPrimitiveTypeReference primitiveTypeReference, ODataMessageReaderSettings messageReaderSettings, Boolean validateNullValue, String propertyName, ODataPayloadValueConverter converter)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightPropertyAndValueDeserializer.ReadPrimitiveValue(Boolean insideJsonObjectValue, IEdmPrimitiveTypeReference expectedValueTypeReference, Boolean validateNullValue, String propertyName)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightPropertyAndValueDeserializer.ReadNonEntityValueImplementation(String payloadTypeName, IEdmTypeReference expectedTypeReference, PropertyAndAnnotationCollector propertyAndAnnotationCollector, CollectionWithoutExpectedTypeValidator collectionValidator, Boolean validateNullValue, Boolean isTopLevelPropertyValue, Boolean insideResourceValue, String propertyName, Nullable`1 isDynamicProperty)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightResourceDeserializer.ReadEntryDataProperty(IODataJsonLightReaderResourceState resourceState, IEdmProperty edmProperty, String propertyTypeName)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightResourceDeserializer.ReadPropertyWithValue(IODataJsonLightReaderResourceState resourceState, String propertyName, Boolean isDeltaResourceSet)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightResourceDeserializer.<>c__DisplayClass9_0.<ReadResourceContent>b__0(PropertyParsingResult propertyParsingResult, String propertyName)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightDeserializer.ProcessProperty(PropertyAndAnnotationCollector propertyAndAnnotationCollector, Func`2 readPropertyAnnotationValue, Action`2 handleProperty)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightResourceDeserializer.ReadResourceContent(IODataJsonLightReaderResourceState resourceState)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightReader.StartReadingResource()\r\n   at Microsoft.OData.JsonLight.ODataJsonLightReader.ReadResourceSetItemStart(PropertyAndAnnotationCollector propertyAndAnnotationCollector, SelectedPropertiesNode selectedProperties)\r\n   at Microsoft.OData.JsonLight.ODataJsonLightReader.ReadAtStartImplementationSynchronously(PropertyAndAnnotationCollector propertyAndAnnotationCollector)\r\n   at Microsoft.OData.ODataReaderCore.ReadImplementation()\r\n   at Microsoft.OData.ODataReaderCore.InterceptException[T](Func`1 action)\r\n   at System.Web.OData.Formatter.Deserialization.ODataReaderExtensions.ReadResourceOrResourceSet(ODataReader reader)\r\n   at System.Web.OData.Formatter.Deserialization.ODataResourceDeserializer.Read(ODataMessageReader messageReader, Type type, ODataDeserializerContext readContext)\r\n   at System.Web.OData.Formatter.ODataMediaTypeFormatter.ReadFromStream(Type type, Stream readStream, HttpContent content, IFormatterLogger formatterLogger)."
}

Any one Knows how looks the Url to create a record in Dynamics?

Note: Description of the entity ac_sejour: URL:

{{ressource}}/api/data/v9.2/entities?$filter=startswith(name,'ac_sejour')

There is Managed solution/Additional Tool for Dataverse which will give you code snippet with actual values for webapi call. Tool is Dataverse Rest Builder

This should give you exact payload with your live data.
