NFON administration portal REST API client

The NFON AG offers a very extensive REST API with almost the same scope as the portal UI. But using the API is a bit complicated, this small package should help with the usage.

[!WARNING] Attention: The use is expressly at your own risk.

Requirements

You need to have

1. the main URL to the API (i.e. https://api09.nfon.com)
2. your API public and (i.e. NFON-ABCDEF-123456)
3. your API secret and (i.e. gAp3bTxxUev5JkxOcBdeC5Absm7J84jp6mEhJZd3XiLdjzoGSF)
4. your account name (i.e. K1234)

[!NOTE] If you do not have this information, please contact your NFON partner for assistance.

[!WARNING] Never share your API secret!

Usage

Install the package:

bash$ go get github.com/art-pub/nfon-api-client

	...
	apiConfig := nfonapiclient.ApiConfig{
		BaseURL: "https://api09.nfon.com"
		Public: "NFON-ABCDEF-123456"
		Secret = "gAp3bTxxUev5JkxOcBdeC5Absm7J84jp6mEhJZd3XiLdjzoGSF"
	}

	var req = http.Request{
		Method:     http.MethodGet,
		Body:       io.NopCloser(strings.NewReader("")),
		RequestURI: "/api/version", // the account name is neccessary for some endpoints and part of the URL path
	}

	_, s, failed := nfonapiclient.Request(&req, apiConfig, false)

	if !failed {
		println("Status is " + string(s))
	} else {
		println("Something failed. Please check your API parameters")
	}
	...

Executed this:

Status is {"href":"/api/version","links":[],"data":[{"name":"version","value":"1.17.5.0"},{"name":"host","value":"api09.nfon.com"},{"name":"buildTime","value":"2023-09-14 16:38"}]}

Result Parser

The result is JSON-like, but difficult to read or process. So as a little help there is a parser for simple results and for multiple results in this package.

Simple Result Parser

For querying the version, the code can be extended from above:

	...
	_, s, failed := nfonapiclient.Request(&req, apiConfig, false)

	if !failed {
		parsed := nfonapiclient.SingleresultParser(s)
		println("version is '" + parsed.DataMap["version"] + " - " + parsed.DataMap["buildTime"] + " - " + parsed.DataMap["host"] + "'")
	} else {
		println("Something failed. Please check your API parameters")
	}
	...

If one executes this, then one receives the following output:

version is '1.17.5.0 - 2023-09-14 16:38 - api09.nfon.com'

The data result is parsed into a simple map[string]string and can be used for further processing.

Multi Result Parser

If you query an endpoint with many results, the multiparser helps to continue working with the result. The usage is as simple as with the single parser:

	...
	apiConfig := nfonapiclient.ApiConfig{
		BaseURL: "https://api09.nfon.com"
		Public: "NFON-ABCDEF-123456"
		Secret = "gAp3bTxxUev5JkxOcBdeC5Absm7J84jp6mEhJZd3XiLdjzoGSF"
	}
	account := "K4711"

	var req = http.Request{
		Method:     http.MethodGet,
		Body:       io.NopCloser(strings.NewReader("")),
		RequestURI: "/api/customers/" + account + "/phone-books?_pagesize=3",
	}

	_, s, failed := nfonapiclient.Request(&req, apiConfig, false)

	if !failed {
		println("API returns " + string(s))
	} else {
		println("Something failed. Please check your API parameters")
	}

	d := nfonapiclient.MultiResultParser(s)
	fmt.Printf("%v\n", d)
	if d.Total > 0 {
		fmt.Printf("First result is: %s: %s", d.Items[1].DataMap["displayName"], d.Items[1].DataMap["displayNumber"])
	}

	// first dataset is linked as d.LinksMap["first"]
	// last  dataset is linked as d.LinksMap["last"]
	// next  dataset is linked as d.LinksMap["next"]
	...

Output:

First result is: Foo Bar: +49 (4711) 0815

Good to know

Datasets and Pagination

Endpoints that return more than one record will return a maximum of 100 records on the first request. The result contains the following information:

Href: Path of the current request

Total: Amount of all datasets (not pages!)

Offset: Offset starting with 0

Size: Amount of maximum results in the response. You can set the amount in the request with the parameter pageSize=XXX with XXX being max. 100.

Query: You filter the results with the additional parameter _q, i.e. /api/customers/K1234/phone-books?_q=SomeName.

Links: Array of links including the first, the next and the last URL to retrieve all data. See LinksMap["first"], LinksMap["last"] and LinksMap["next"] in the example above.

[!IMPORTANT] Please note: You have to iterate through all those links to retrieve all data. Just repeat with the next given Href until your current Href (path of the current request) matches the last entry.

[!IMPORTANT] If the last entry is empty, you already have all data in the current response.
