I am trying to create an API in Tyk on Premise Community Edition using Gateway REST API as per the tutorial, but after executing the command

curl -H “x-tyk-authorization: {your-secret}”
-H “Content-Type: application/json”
-X POST
-d ‘{
“name”: “Test API”,
“slug”: “test-api”,
“api_id”: “1”,
“org_id”: “1”,
“auth”: {
“auth_header_name”: “Authorization”
“definition”: {
“location”: “header”,
“key”: “x-api-version”
“version_data”: {
“not_versioned”: true,
“versions”: {
“Default”: {
“name”: “Default”,
“use_extended_paths”: true
“proxy”: {
“listen_path”: “/test-api/”,
“target_url”: “ http://httpbin.org/ ”,
“strip_listen_path”: true
“active”: true
}’ https://{your-tyk-host}:{port}/tyk/apis/ | python -mjson.tool

with the required values, I am getting error “No JSON object could be decoded”.
Any idea why this error is coming??

Hi Tanaya,

It’s likely that this error was caused by the format of the cURL request itself. The newline character in particular is often interpreted differently depending on the type of terminal used. It may be worth re-writing the request so that the entire command is on the same line or adding a backslash to the end of each line before sending the request. There are also third-party tools available like Postman which can make writing longer cURL requests much simpler.

Hope that helps.

Kind regards,

Hi Martin,

This is my single line command

curl -H “x-tyk-authorization: 352d20ee67be67f6340b4c0605b044b7” -s -H “Content-Type: application/json” -X POST -d ‘{“name”: “Test API”, “slug”: “test-api”, “api_id”: “1”, “org_id”: “1”, “auth”: { “auth_header_name”: “Authorization”}, “definition”: { “location”: “header”, “key”: “x-api-version” }, “version_data”: { “not_versioned”: true, “versions”: { “Default”: { “name”: “Default”, “use_extended_paths”: true } } }, “proxy”: { “listen_path”: “/test-api/”, “target_url”: “ http://52.44.115.34/e-cart/rest/default/V1/categories ”, “strip_listen_path”: true }, “active”: true }’ https://10.0.0.209:3000/tyk/apis/ | python -mjson.tool

I’ve figured out what the issue was on my end and maybe this helps any of you guys.
We have a corporate proxy server setup (we probably aren’t the only enterprise).
This has always been a pain to me, but hey I’m no sysadmin.

For this we need to set some exports to make sure we can reach
the outside:

export http_proxy=http://user:pass@proxyhost:3128 export https_proxy=http://user:pass@proxyhost:3128

After I was going through the lines of the bootstrap.sh I saw
the return value was both quite big and somewhat familiar.

The system was trying to go through our proxy in order to get to itself (duh! That is what I had configured to be able to retrieve tyk from the internet)

In order for this to not happen for local connections I added
this line to my .bashrc (where I also had the http_proxy settings)

export no_proxy=localhost,127.0.0.0/8,10.31.12.38,10.0.0.0/8,apim.localdomain.nl

After that I ran below command and what do you know…
`[root@apim ~]# /opt/tyk-dashboard/install/bootstrap.sh apim.localdomain.nl

Not sure about any HTTP proxy on my part, but just trialling this TYK API, and also have come across this snag just now.

Installed without a hitch (my centOs VM)

Attempted the API creation via CMD,

curl -H “x-tyk-authorization: 352d20ee67be67f6340b4c0605b044b7” -s -H “Content-Type: application/json” -X POST -d ‘{“name”: “Test API”, “slug”: “test-api”, “api_id”: “1”, “org_id”: “1”, “auth”: { “auth_header_name”: “Authorization”}, “definition”: { “location”: “header”, “key”: “x-api-version” }, “version_data”: { “not_versioned”: true, “versions”: { “Default”: { “name”: “Default”, “use_extended_paths”: true } } }, “proxy”: { “listen_path”: “/test-api/”, “target_url”: “ http://http ://httpbin.org/”, “strip_listen_path”: true }, “active”: true }’ http://127.0.0.1:8080/tyk/apis/ | python -mjson.tool

Errors out.
No JSON object could be decoded

Looking at logs, not events whatsoever
And im tailing the lot of them via
tail -f /var/log/tyk-*

Tips Pointers appreciated

Hi @pantsjj ,

My colleague and I have been unable to reproduce this error message. Could you please try running the cURL request without -s flag and without the | python -mjson.tool at the end? I think the error message you’re currently getting is being produced by Python and all it really tells us is that it was unable to parse a JSON object from the cURL request. If you remove that part of the request, hopefully the error produced will provide more of a clue as to what’s going on.

Kind regards,

i may be getting somewhere.

( i typed above twice) yes. this works. same copy paste as i mentioned earlier.
I did however reinstalled everything from ground zero. perhaps, some indeed some issue with services, which logging didn’t show.

** “action”: “added”,**
** “key”: “1”,**
** “status”: “ok”**

i can query the api’s (test api not listed, despite earlier OK, but demo/example one is (as from the ./apps/example one.

curl -H “x-tyk-authorization: 352d20ee67be67f6340b4c0605b044b7” “ http://127.0.0.1:8080/tyk/apis/1 ” | jq
“name”: “Tyk Test API”,
“slug”: “”,
“api_id”: “1”,
“org_id”: “default”,

---- long story short,

i note that dashboard is not reflecting what the curl is responding with.
As per example above, this information is nowhere to be found in the dashboard. in fact, i have some other API demo example(as, so named) listed there,

ok. This particular topic is then closed.
Moving this to another relevant topic thread.

Basically, dashboard and gateway are talking to two different things.
Gateway, (as per above CLI) is up and running with the json example

But on Dashboard, it isnt showing. furthermore, i am unable to successfully create any further API via dashboard. see my debug below. so. moving to another thread in any case.

Thanks for all the help thus far

It looks like you are using the gateway api and have the gateway configured to run without the dashboard. So the two are completely disconnected.

If you run CE - there is no dashboard, and that’s what the instructions in the tutorial optimise for.

To use the dashboard it might probably be best to run the setup script again from the dashboard installation and setup guides.
