Kindly provide me with helping material you can

Thanks in Advance.

If you have used

$config['rest_enable_keys'] = TRUE;

in your config/rest.php file then make it FALSE

$config['rest_enable_keys'] = FALSE;.

Because it seems like you have issue with keys.

Key Table

CREATE TABLE `keys` (
    `id` INT(11) NOT NULL AUTO_INCREMENT,
    `key` VARCHAR(40) NOT NULL,
    `level` INT(2) NOT NULL,
    `ignore_limits` TINYINT(1) NOT NULL DEFAULT '0',
    `date_created` INT(11) NOT NULL,
    PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
