Here some support for the plugin:

Version 3.4.9 (August 31 2018), see in detail here:

pro plugin is ok with wordpress 3.4.9
pro plugin is ok with gutenberg plugin 3.6.2
added Information on General Data Protection Regulation (GDPR): see Plugin-Options Tab "GDPR"
added links to HowTo-Videos: https://json-content-importer.com/support/videos-on-json-content-importer/
creating custom post types: uniquekey can be placed in cpt-parameters as "key" - instead of custom fiel value ("jci_uniquekey_createpost")
new shortcode-parameter displayapireturn: put api-return as string into JSON and access via {{data}} (e.g. if api delivers raw encoded image-data). displayapireturn=1 (pass directly), displayapireturn=2 (pass base64_encoded), displayapireturn=4 (remove linefeeds)
if shortcode-parameter addpostdata2json=y then the array "jcipageparam" is added to the API-JSON to get access to the WP_Post OBJECT (get_post) like ID, post_date...
improved debugmode

Version 3.4.8 (April 29 2018), see in detail here:

Admin error message, if database-update from version 3.4.7 on requires a deactivation-then-activation of the plugin.
Code for using CURLOPTIONS (esp. HEADER and POSTFIELDS) completely rewritten: If you use CURL-POST/GET-API-Requests and CURLOPTIONS check if all is ok, please.
New Shortcode-Parameter: maskspecialcharsinjson=no switches off some usually very good handling of JSON (rare JSON needs that)
New Shortcode-Parameter: httpstatuscodemustbe200=no accepts that some APIs deliver valid and usable JSON and and http-error (ok is 200). Without that the plugins says: No http-ok from the API, hence ignore JSON.
Several Bugfixes: Templatemanager, sorting JSON with twig-extension, use of CURL-Options
